I understand that you mean attach an image to a post on this forum (these are postings rather than email - sorry if I'm being to bleedin' obvious and you know this already).
I think you need someone to talk you through the process. Let us know if you want to call someone - might be easiest to solev the problems over the phone - but don't post a phone number in the open forum pages - you can use the Private Messages area for that.
