I'm using Vista and IE7 and the forum (or my browser) automatically resizes the pics to my screen width, so I can't see them in their full glory. If I right click I don't get an option to "View picture" although I have heard some people doing this? It works in Firefox though, so I either open Firefox to view the pics in the photo competition, or I copy the url of the pic and paste it into a new window, and I can see it full resolution there.
I know what you mean because the re-sizing causes the picture to appear jaggy (no anti-aliasing or something?) and they need to be viewed at the full resolution, especially photo competition pics.
