Yeah, use Photobucket, Flickr, Webshots and all those kind of free sites. You can almost upload unlimited pics there... One point: If you delete a pic there, it dissapears here too....
If you want to post a pic from the web: Just post it's url between these: [ IMG ] and [ /IMG ]
So put the URL between the two and de;lete the spaces between bracket and IMG. I had to do the extra spaces, otherwise it didn;t work....
