Video stills taken from GoPro videos are in jpg format. When members try and upload these specific images to my forum they do not Onebox or even display at all (end up as a non-clickable url).
The thing is, they work fine here.
All other images (i.e., non GoPro video stills) work on my forum just fine. Oddly enough, if I take the offending GoPro jpg and export it without making any changes (again, as a jpg) from any image editor then the same image displays just fine.
What am I missing?
