Hi,
I have some binary images stored as 64-bit strings in my database. I'm using SQL to convert this value to a Byte[] (array) and I'm using a radbinaryimage control within a listview that is databound to my openaccesslinq data source. (and this is pointed to the data field containing the byte[].) It appears to be working except, Instead of my image showing it's showing a broken image icon as shown in the screenshot attached. I have no idea how to troubleshoot this, but I did notice something strange. When I right click on this image and click "open in new tab" chrome begins a download of a file called "Telerik.Web.UI.WebResource.axd" If i view this file in a text editor, it's actually the 64-bit string that is the original value in my database. This doesn't make sense though, because i'm converting it to a byte[] within the view I'm using, the radbinaryimage control should never see the 64-bit string. So i'm wondering, does radbinary image convert from a byte[] to a 64-bit string to display the image? If so, is there a way to simply use the 64-bit string that I already have in the database?
Either way, does anyone have any advice on how to troubleshoot this?

Hi Brandon,
I saw and answered your support ticket on the same issue. If you have further questions, please post them there.
For others who might be interested, here is the main part of the reply:
As long as you provide a valid image through the byte array, you should not have a problem with displaying the issue, except for the cases where your site operates on a WebFarm or WebGarden environment (these are unsupported by RadBinaryImage).
If you are not sure how to check the image, you could see if it is correctly displayed when streamed through a custom http handler, as the one shown in this thread:
