They probably want you to clear your internet cache, which is in the "Tools" > Internet Options menu if you are using Internet Explorer.

Bob, your browser has a cache that stores temporary internet files. I'll post a link for Microsoft Internet Explorer or you can google "browser cache" with the name of whatever browser you use.

To post more than one pic at a time, just do whatever you do to post one pic ... then do it again with the next pic url in the same post. Hope this helps.

Here is a link that might be useful: Clearing your cache - MS Internet Explorer

Bob, to post more than one photo at a time, it helps to open your photobucket in a separate window, that way you can post as many as you like by switching back and forth from your forum window to your photobucket window, without having to close either window, thereby creating the ability to post more than one photo in your message. Hope this helps.

Bob,
I found that if you right click on the tag you want and then left click on select all, it will high lite the tag, then if you left click on it again and select copy it works. It seems to be working again now though.
