Boeing:
Most of the kind replies you have received have missed the fact that your wife wishes to post to "a similar forum to pprune".
Now Pprune does not allow posting attachments (for webspace and bandwidth issues which I can appreciate). But your wife's board may allow these. If so, you can download them directly from your hard drive (if the Administrator permits).
I am on several
vb boards, some of which allow attachments, some of which don't. You can tell by looking at the "options" that mention IMG code, Smilies, and so on at the footer of posts (where these appear seems to vary according to the Admin's set-up, but they are there somewhere).
Good luck.
edit: here's what the options look like
