I am attempting to upload images of a multi-target. I keep getting an error with certain images that have been edited in Adobe Photoshop CS6. the error message in Target Manager is 'Uploaded Image is Invalid.' Alpha channel is not used the colour space is RGB, I have set Adobe to not use color management. However I still receive this error message. The images that worked earlier were utilzing 'sRGB' and still worked (according to finder 'Color LCD' is being used for those images). I have tested different profiles with no luck, any help would be appreciated as the error message is quite vague.
I am happy to PM the images if required.
