More avitar and sig. pic problems

[Zanrel]

There's no problem with my pics, and I made sure that I typed the right address. I'm trying to say that my pictures works and that I saw it when I post. But later after I leave and come back to the forum in an hour or less, it doesn't show anymore? Now when I viewed the pics in a window and went back to the posts that I made to see if the pics showed, the pics was shown. And then it disappears again after awhile, so I view the pics on the windows again. And it showed again, but later disappears. So I view gain, and same thing happens over and over and over. And I didnt do nothing but just that, I didnt even to go options. It just appears whenever I view the pics on the window, as if there is a timer of how long it should be shown and then it disappears. Is that how it works, because I dont want to keep viewing the pics on a window every 2 minutes or so just so the pics will show. That would suck
