Error Showing Image Attachments

All,

After upgrading, when I upload an image and attach it to a ticket,
everything seems to work fine, but when I click on the attachement to
view it, I am taken to a blank page that says “The image ''
cannot be displayed, because it contains errors”, or it will just give
the Image URL. This is also true for images that have been uploaded in
our pre-migrated RT system.

Thanks.
