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

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.

To export a gridview to a image,
1.First export gridview data to pdf.
2.Then convert it into image.
I have stored my image in database as format, how do i retrieve the image to imagefield without using gridview or datalist? I just want to retrieve it to the imagefield only
You can use the httphandler to retrieve the binary image, and then bind it to one image contorl with src property. Check this link.

I don't want save image in database. My application going to work on different shops i want show their logos on report.rdlc. For that i want to know, can i show image on report.rdlc by using path of image only? I tried to create parameter for Report.rdlc in ReportData but there is not any image Datatype.
Yes, you can:
Set image Source to External
Set image Value to an URL or file path
Set EnableExternalImages=true in your report code
You can also refer to http://msdn.microsoft.com/en-us/library/ms251715(v=vs.80).aspx for some additional info, but those steps above must be enough.
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
