They are not the exact same images. In some images I edited out the speech bubbles (like this one), in others I improved the framing, and all of them have better resolution. For example, Sadurang (Earth-616) from Tony Stark Iron Man Vol 1 12 004.jpg might loook like the exact same image as the version you uploaded, but it's roughly 265,99% bigger.

I would have replaced the images conventially, but I work with JPG, which is also the most suitable format for this kind of images, whereas the images you uploaded were PNGs.
