Hi piggerjane, first you need to resize the pic, just click on the link below, the first resizer is for XP and a few posts down is one for Vista. Once resized just follow these instructions and you should be right.
Instructions on posting pics. Under where you type a reply click on BROWSE, choose your resized pic, then click on ATTACH THIS FILE, a small pic will show just above browse then, beside this over on the right hand side click on ADD TO POST and it will put the pic in your post, repeat for additional pics.
