Not sure what you guys were doing, but I’ve been using flickr for years and never had a problem linking highres stuff. The most I usually upload is 3008x2000. Example:
Maybe it’s the personal page you can’t see the link for the full version. Like if I were to go to JayS’s page and try to click on the “original” size for that photo. I never had an issue uploading it at full resolution.
I sign into flickr with my google account. The last Yahoo account I had was to edit stuff in geocities…needless to say I didn’t feel like using that again.
^ Seeing the full rez photo on someone else’s flickr page is a setting each user can select. I don’t block mine but a lot of people don’t allow access to anything over say 1024.
I know when Walker went nuts right after getting his SLR I was able to access his high res shots.
