The best (IMHO) is to set up a photobucket account (
www.photobucket.com) and link the pictures from there. Maybe this should be made a a sticky?
All you have to do is this:
1-create an account.
2-upload the pictures from your computer into an album that you have to create.
3-select the pictures you want to post and it will upload them. It takes a bit so be patient.
4-once the pictures are uploaded and in your album, hover over the picture with your mouse you'll see a box to check. You'll now see that the little picture has a blue box around it.
5-scroll to the bottom of the screen and you'll see in blue text "choose action" and a down arrow, click that and select "generate link codes for selected".
6-this will open another window and then you will see "IMG for bulletin boards & forums". You can copy the link from either the clickable thumbnails or full size and paste that into a thread here.
It sounds harder than it really is, give it a try.
