OK .. firstly welcome to passionford
easiest way is to use
www.tinypic.com
you upload the pics via their site and there will be a tab next to it that once all have uploaded will say copy.
you copy each link it gives you per picture for bullettin boards and paste up into a new thread ...
hope that helps ... it is one of the easiest ways to do it ..
or you could use passionfords own uploading service
