When I looked at your first listing, the initial photo was clear and smooth, but the other two photos where highly pixelated. The appearance is that of too much sharpening, where white pixels appear around dark areas. The other photos where progressively worse - and the same when I panned through the overlay of photos.
Then I looked at your second listing and it was showing the same pattern, but as I was looking at the enlarged photos, they cleared up. There appears to be progressive image loading in play, which is intended to show a coarse image that progressively fills in the rest of the dots to make a smooth image.
When I went back to the first listing, all the photos were smooth, so that means they finished loading.
Because the same image showed progressive loading in other browsers, it appears eBay could be providing progressive loading to your PNG images. PNG image files are a lot larger then JPG image files, so eBay may be doing this to reduce loading time. Have you tried the same with a JPG image instead?
However, I also see compression artifacts in some of your images. Some appear to be more compressed than others. Compression artifacts (pixie dust and cross hatching) can appear more prominently in images with smooth color gradations (like your file folder) than in busier photos like a flowered dress. If you uploaded JPG images it would be interesting to see if the compression was the same.
