I have XP; the operating system you mean? I was able to post some photos back a few yrs but the photo hosting service died and that was the last time I found I could post pictures. I am sure if I spent many hrs tracking down a service and learning to use it I could get it going; but is it worth the trouble? Posting PSUD results would be great except I am sure not many would bother to read them anyway. If I need to send a photo I just scan it. Other than that I havn't had a need to do this up until now.
