Has anybody come across the following phenomenon: I designed a webpage on my PC, with a number of images in .jpg format. The page was fully validated by W3C. On my PC all images show up fine. When you click on each, a larger image shows up in a popup-window. These popup-windows are not blocked by any of the regular browsers (IE, Avant, Opera, Firefox). When I upload the page and its images to the website, none of the regular small images work when uploaded (100x70 or 100x100 pixels). They just show up as an "x" placeholder. But the enlarged images (545x680 or 700x525 = WxH) come up fine. As I said, it works fine on my PC, does not work when on the host. The pictures were uploaded in binary format. Suggestions anyone?
