Fur--Thanks for the tip; but I did ftp it in binary instead of ascii. In the meantime I've put my files on another web server where they work fine. Seems to be a problem with just SOME web-server software. Now the question is: which kind? Also, since web-browserimage viewers for other common image file types don't seem to be stymied by my MetaStream-"problem" server, I think MetaCreations needs to tweek their MetaStream viewer software to be compatible with a broader range of server software. I've gotten no satisfactory answer yet from MetaCreations; but since MetaStream is their BIG up-and-coming company focus, you would think they would be responsive to such a problem. Many of my potential "MetaStream"-file customers are using a web-page server that won't allow me to display MetaStream files. Leaves me in the lurch!
