At first i log in from the main page at talkbass.com/forum, if i remember correctly. Doing this i'm only viewing my own profile, and after that i have to log in again, from another place, like the "my profile" section (which seems pretty much the same as the former profile-viewing-page).
Then i checked out the pictures, and for my great amazement - was asked to log in before viewing the pictures....
I couldn't find any note of anyone having the same problem, so is it the god-damn Internet Explorer again or some other stuff?
