We've got a few sites where I work which use an image filter which generates and saves the cropped image without an extension.
In IE9+, the images display correctly when displayed directly on the page, however, when you click to view the image only the image doesn't display and instead fires up notepad showing the raw image data.
I've solved this issue in the past, but cannot remember how, nor where I found the help.
Do any of you know how to get around this issue?
Uploading the images again is not a viable solution as there are too many.
