Without you sending me a photo that's impacted by this there's nothing more I can do (it needs to be raw format from the device so zipping it and uploading to 3rd party service or emailing zip is likely necessary). I do not own an Apple product. I've tested 2 image libraries that utilize EXIF orientation of which they all work fine now. This behavior is in the JS though so please be sure after updating CB Gallery you purge any and all cache on your site to be sure the JS wasn't cached by Joomlas caching functionality or 3rd party template caching functionality. Your other components may not even have client side resizing so the issue could be entirely irrelevant there.

Ok, was able to confirm the issue with the photo you've sent. I'm unsure what's causing it yet, but seams to be the client side resizing as once disabled it works fine. The photo is quite large though so maybe hitting limitations of the browser being able to handle it or some errors in the orientation code. Have added a bug ticket to further investigate and fix.

Hopefully I can have this fixed today.

Ok, I believe I've tracked down where it's going wrong. I'm attempting to handle the rotating, cropping, and resizing all in a single pass. It doesn't like that. The resizing (to enforce max width/height) conflicts with the orientation code. So I'm now doing this in 2 passes. First it immediately checks if there's an orientation. If there is it'll immediately rotate the image before doing anything else. No resizing, cropping, etc.. applied. It then continues with the rest of the behavior (resize/crop) then sends it to the server for upload. This appears to be working fine now with the image you supplied and all my test orientation images working correctly.

This is now fixed in latest build available now.
