I am aware of the fact that it's the software used in creating or saving the images. I merely bring this to your companies attention for the sake of assisting to improve upon a wonderful product. If your company decides to utilize resources to allow more flexibility in the types of compression of images that are allowed, that's your call. It appears that not all image editors are created equal, despite adhering to some standards.
I can and have gotten the image uploader to work, so I do not have an issue with making sure that my users are well aware of the fact that different types of compression may not work.
Thank you for your time.
