Upload image in folder and rename it

I have created a interface where user will select and upload image. But how can i rename and save image in server folder(images), and display it again on my image gallery page. My website is developed in asp.net c#.Suggest me some ideas or links to refer.
upload button click code below:
protected void Button1_Click(object sender, EventArgs e)
{
if (FileUpload1.HasFile)
{
string fileName = Path.GetFileName(FileUpload1.PostedFile.FileName);
FileUpload1.PostedFile.SaveAs(Server.MapPath("~/uploads/") + fileName);
Response.Redirect(Request.Url.AbsoluteUri);
}
}
Thanks.

You will need, obviously, a folder somewhere in the website's directory. The user who is running the application pool for the web application will need read/write access to it. Depending on your needs, you may not want this folder to be browsable directly by users (other than the user running the application pool).
You will need to store the new file path somewhere (database, XML file, flat text, etc.) so when the user requests to see the image, you will open this file, and return it in the response stream as its proper type (JPG, GIF, BMP, etc.) so the user is prompted to open it or save it.

For Rename and save image in server folder try below code : -
//Get Filename from fileupload control and rename it
string filename = ((DateTime.Now.ToString().Replace("/", "-")).Replace(":", "")).Replace(" ", "_") + "_" + ((Path.GetFileName(FileUpload1.PostedFile.FileName)).Replace(".",".")).Replace(" ","");
FileUpload1.SaveAs(Server.MapPath("~/uploads/" + filename));

Converting aspx page to image file

I have c# dynamic aspx page after new property add I create for record brochure
http://veneristurkey.com/admin/Brochure.aspx?Admin=PropertiesBrochureA4&id=36
but I want to this convert image file I am searching on internet but all with webbrowser and windows forms. I need on page load show not css type also image file. jpg, png or tiff how i can do this. i need to see sample code..
saving aspx page into an image 2

As I mentioned in my comment, your best bet is to opt for attempting to render HTML to an image.
Here is the link for a library that will allow your to render html to an image:
http://htmlrenderer.codeplex.com/
Here is code that does exactly what you're asking:
http://amoghnatu.wordpress.com/2013/05/13/converting-html-text-to-image-using-c/
Now all you have left is to get the html, since I'm assuming you don't want this to render to the browser prior to generating this image - you should look into grabbing the rendered html from the aspx page on the server prior to returning it, and then just return the image. To render a page:

Sorted.

If you do not mind using a commandline tool you can have a look at wkhtmltopdf. The package include a wkhtmltoimage component that can be used to convert HTML to image, using
wkhtmltoimage [URL] [Image Path]
Codaxy also wrote a wkhtmltopdf c# wrapper available through the NuGet package manager. I'm not sure if the wkhtmltoimage component was included, but it should be easy enough to figure out how they wrap the wkhtml components.

i fixed my problem with screenshot machine API they are my code..
public void resimyap()
{
var procad = WS.Satiliklars.Where(v => v.ForSaleID == int.Parse(Request.QueryString["id"])).FirstOrDefault();
var imageBytes = GetBytesFromUrl("http://api.screenshotmachine.com/?key=xxxxxx&size=F&url=http://xxxxxxx.com/a4.aspx?id=" + procad.ForSaleID);
string root = Server.MapPath("~/");
// clean up the path
if (!root.EndsWith(#"\"))
root += #"\";
// make a folder to store the images in
string fileDirectory = root + #"\images\a4en\";
// create the folder if it does not exist
if (!System.IO.Directory.Exists(fileDirectory))
System.IO.Directory.CreateDirectory(fileDirectory);
WriteBytesToFile( fileDirectory + + procad.ForSaleID + ".png", imageBytes);

Yes i also try wkhtmltopdf c# wrapper but in pdf or image converting time my computer fan goin crayz. also i must upload server exe file and my hosting firm didnt support them

Enabling a user to download a file

I am working on an image gallery, and on the browse image module, I have a download icon. I need it to behave as a download button. When the user clicks on it, they should be presented with save file dialog, or the file should be downloaded using their default browser download set-up.
I tried many ways, but no luck.
The download Icons appear in a Modal-popup and hence all code is wrapped inside UpdatePannel
These images are of different formats (jpeg, gif, tif, psd)

Look at http://www.codeproject.com/Articles/74654/File-Download-in-ASP-NET-and-Tracking-the-Status-o or Best way to stream files in ASP.NET

Finally sorted out with :
A) To download a file at Client Location :
public void downloadFile(string fileName, string filePath)
{
Response.ContentType = "application/octet-stream";
Response.AddHeader("Content-Disposition", string.Format("attachment; filename=\"{0}\"", fileName));
Response.WriteFile(filePath + fileName);
}
B) Since the function triggering controls(imgDownload, imgDownloadPsd) are wrapped under async call : Add this to Page Load :
protected void Page_Load(object sender, EventArgs e)
{ ScriptManager.GetCurrent(this.Page).RegisterPostBackControl(imgDownload);
ScriptManager.GetCurrent(this.Page).RegisterPostBackControl(imgDownloadPsd);
}

Creating a hyperlink to a physical path on the local PC, to files not part of the web site

I have some files in a folder on the harddrive, like C:\ExtraContent\ that has some PDF files. This folder is not part of the website. I was able to successfully upload a PDF to this folder using the default ASP.NET FileUploader, no problem.
What I would like to do is, create a hyperlink that links to a PDF in that folder C:\ExtraContent\somePDF.pdf
I am able to get close using a Button with the following code:
protected void Button1_Click(object sender, EventArgs e)
{
WebClient client = new WebClient();
Byte[] buffer = client.DownloadData("C:\ExtraContent\somePDF.pdf");
Response.ContentType = "application/pdf";
Response.AddHeader("content-length", buffer.Length.ToString());
Response.BinaryWrite(buffer);
}
The above works in terms of opening the file. But I can't get this to work with an ASP.NET HyperLink.
The reason I want to use a HyperLink is so that the user can choose to right-click and Save As, to download a copy. If HyperLink controls can only link to relative paths, what can I do to get my desired result?
Note: making the files I'm trying to access part of the site is not practical for us.

Basically allowing access to the folder the way you describe is a real security risk (because it requires hacking at the permissions), isn't trivial and in general should be avoided. The way that you achieve your desired behaviour is something along these lines.
Firstly create a blank aspx or ashx page.
Secondly, either in the Page_Load or ProcessRequest you want to use code along the following lines
string filePath = "c:\\Documents\\Stuff\\";
string fileName = "myPath.pdf";
byte[] bytes = System.IO.File.ReadAllBytes(filePath + fileName);
context.Response.Clear();
context.Response.ContentType = "application/pdf";
context.Response.Cache.SetCacheability(HttpCacheability.Private);
context.Response.Expires = -1;
context.Response.Buffer = true;
context.Response.AddHeader("Content-Disposition", string.Format("{0};FileName=\"{1}\"", "attachment", fileName));
context.Response.BinaryWrite(bytes);
context.Response.End();
I haven't tested this and taken it from my head so it might need some tweeks but the above code should get you on the right track to cause the persons browser to begin downloading the file you provide.
EDIT: I just realized (after rereading your question) your problem was slightly different to what I thought, to get your issue resolved simply make the hyperlink button you are using link to a page that can process the request as described above. IE: An ashx or aspx page

You need to create a hyperlink to a page that acts as a 'proxy' so that the page will return a response that contains the file stream.
You cannot create a link to a file that is not prt of your site.

Accessing image from other server

I have image file placed on the one server and application on other server.
I want to access that image, below code I have written:
On default.aspx, I have
<asp:Image ID="Image1" runat="server" ImageUrl= "GetImage.aspx?imgName=MyImage.jpg" />
and on GetImage.aspx, I have written the below code on page_load
protected void Page_Load(object sender, EventArgs e)
{
// Changing the page's content type to indicate the page is returning an image
Response.ContentType = "image/jpg";
var imageName = Request.QueryString["imgName"];
var path = "//SERVER/FOLDER/" + imageName;
if ((string.IsNullOrEmpty(imageName) == false))
{
// Retrieving the image
System.Drawing.Image fullSizeImg;
fullSizeImg = System.Drawing.Image.FromFile(Server.MapPath(path));
// Writing the image directly to the output stream
fullSizeImg.Save(Response.OutputStream, ImageFormat.Jpeg);
// Cleaning up the image
fullSizeImg.Dispose();
}
}
But I am getting error at
fullSizeImg = System.Drawing.Image.FromFile(Server.MapPath(path));
Please let me know where I am incorrect. Do I need to anything else other than Server.MapPath ? because my image is on other server.
EDIT
I have image folder in my computer
I have created a web app in other computer [same network], deployed
in IIS, image is displayed correctly. With path like
http://10.67.XX.XX/websiteName/Default.aspx
but when I am trying to access the same from my comupter or any other
computer, I am not able to see the image.

You shouldn't use Server.MapPath. This is used to map virtual paths under your site to physical paths under file system. If the file exists on another server, just access it by name directly, without Server.MapPath.

The answer above is incorrect because the images reside on a separate server.
So System.Images will not no where the image is.
Secondly you have to use server.Mappath for system images, it requires a windows path i.e. c:\blah\blah\whatever.jpg.
you will need to use \\server\C$\folder\image.jpg this works well with system.image.FromFile
Also saving you can also utilize this.
