load dynamic image from path in crystal report

I want to show an image in my report , I save path of image in my sqlserver database and now I want to load image from path .I search all of internet for that and try all of guidance , I first insert image into my report and after that I go to >Format Editor > picture > Graphic Location > and insert path of image into the textarea like this {Command.path} but when I run , it doesn't show any picture . Now how should I do ?
I use visual studio 2013 and latest version of crystal report .

Use a conditional formula to dynamically change the location of a report’s image.
1. Add an image to the report: -> Insert -> Picture
This image will act as a placeholder.
Ensure that the placeholder is the same size as the one that will be dynamically loaded, otherwise, the image will be scaled.
2. Change the image’s Graphic Location:
->right click image
->select Format Graphic…
->select Picture tab
->click the conditional-formula button (looks like x+2)
->set the formula’s text to the name of the formula or parameter field that will contain the image’s URL
->save the formula and click the OK button
->Save the report
It worked for me.

You can actually do it by:
Add a datasource for your report. Be sure to include the path image.
Add a default image.
From Format Editor > picture > Graphic Location , add the path image field.

According to this, you're doing it right. Perhaps try to set a formula field equal to {Command.path} and use that instead to see if crystal just isn't parsing it properly? That way you can display the formula field and see how it displays. Perhaps you're storing it in the DB with quotation marks or spaces? Alternatively, using a parameter should definitely work, so you could make a sub-report with {Command.path} as a parameter that it uses to load up the image.

NotShowing Data-Bound Image (Reporting Services)

I Create an SendWorkOrder.rdl Report for SSRS. In the dataSet I have a field with Image dataType(Value in that database column eg- 0x89504E470D0A1A0A000000....).
Followed msdn article to create data bound image.
I Tried following expressions, But Image Not Showing
=First(Fields!Signature.Value, "CasingList")
=System.Convert.FromBase64String(Mid(System.Convert.ToBase64String(Fields!Signature.Value),105))
=Convert.FromBase64String(First(Fields!Signature.Value, "CasingList"))

You are trying to create an image in your report from the database?
I assume you have set up an image control as follows
Then set the field to be a reference to your 0x89504E470D0A1A0A000000... data
=Fields!Marker.Value
And the Mime type to the the corresponding image format
=Fields!Marker_Type.Value
(note this should be something like image/jpeg or image/png)
Without the image format nothing will render.
A set up such as the above should render correctly, as shown

dynamic image in rdlc not appear correctly

I have this hirarcy in my project
Report forlder -> Image Folder , Reports -> Rdlc
in rdlc I set the image source to external and use parameter
when add the parameter to report call the report not appear
I write the parameter like
"file:images\icon.jpg" is there an certain extension to use or why this cause the report to not appear ,I tried to remove the image and the report work fine

you should pass the complete image path to your image in this way if you pass it like you've done I don't thik it will work.
ReportViewer1.LocalReport.EnableExternalImages = true;
ReportViewer1.LocalReport.SetParameters(new ReportParameter("image", "file:///" + Server.MapPath("~/images/icon.jpg",true));

How to Fill FileUploader Default Value

I need a help to fill FileUpload Default file path using C# code
here is a file path Server.MapPath("~/DemoTrack/DemoWorkout.mp4");
which i want to fill in FileUpload by code of C# if the FileUpload value is null. in asp.net
please let me know how can I fill the FileUpload by code
I'm doing this
FileUploadDemoVideo.SaveAs(Server.MapPath("~/DemoTrack/DemoWorkout.mp4"));
FileUploadAudio.SaveAs(Server.MapPath("~/DemoTrack/DemoTrack.mp3"));
String DfileExtension =
System.IO.Path.GetExtension(FileUploadDemoVideo.FileName).ToLower();
String AudioExtension = System.IO.Path.GetExtension(FileUploadAudio.FileName).ToLower();
i want to FileUploadDemoVideo and FileUploadAudio by code this is a file path Server.MapPath("~/DemoTrack/DemoWorkout.mp4") which i want to fill in FileUpload with a code wright in c# i just want to fill a FileUpload control then i can get a fileName and Extension so can convert in a Default value in byte[] and store that byte in sql data base if use didnt select the any file using FileUpload the Default value audio and video byte will be saved in database. as per that file which i fixed for audio and video.
I want to add a fix audio and video fill url in both audio and video FileUpload control with the code.

According to my understanding, you want to save the default audio & video, if there is no input from the user. If this is the case, you can directly save the file onto database without involving your file-upload control. Filling the default file path on the file-upload control doesn't make any sense on client machine, since your default contents resides on server.

How can i search for the Image that was given in Binary format and if exists i would like to display the data in Gridview

If any user gives the information of his photo in binary objects how can i search it and how can i display the corresponding image that was stored in the sql database

I will suggest to create a CRC/Hash of the Image File and then just search for this number. If you found it then compare the full Binary Format to be 100% that is the same.
To display the image I suggest to create an .ashx handler, that you send the ID of the image encrypted, then inside the handler you read the Image from the database and send to an img anchor.
eg.
<img src="MyImageHandler.ashx?Id=7738akj12391723">
I found some existing examples for display the image from the Database
