How to display images in repeater from database

Question

Can anyone tell how to display images in repeater control from database (binary stream)?

Answer 1

Use/learn HttpHandler.

Steps:

1. Develop an image handler and register it in web.config
2. Test it (handler) via url.

Answer 2

I would create a handler that returns the image something like this:

 System.IO.Stream responseStream =//stream from database
 MemoryStream mem = new MemoryStream();
 CopyStream(responseStream, mem);
 byte[] buffer = mem.GetBuffer();
 context.Response.Clear();
 context.Response.AddHeader("content-disposition", "attachment;filename="image");
 context.Response.ContentType = "image/PNG";
 context.Response.BinaryWrite(buffer);
 context.Response.End();

and then in your repeater i would call the handler something like this:

<img src="handlerName.ashx?id=<%# Eval("Id")%>" />
