Hi there Flo! Welcome to the forum!
We're glad you're here and you'll definitely find some friendly AC collector's around here!
To upload pictures you can click the "yellow mountain" looking icon when editing your post and then just post a direct link to your picture there! Or if you prefer to write it manually just use the
[ IMG] (without the space) and
[/ IMG] (without the space) brackets and put your link in-between. Hope that helps!
Edit: Also I should specify that by "direct link" I mean the link to your picture on the web somewhere, not on your local PC
