I've had this issue before and always kind of ignored it but it really seemed noticeable in this case. I upload images but find that they look different than the image on my computer. I have a link showing a comparison between the image on my computer and the image once it's been uploaded.

I've uploaded the image as .jpeg and .png but the same problem occurs. Does anyone else have this problem or know of a fix?
