Thanks lads.
Jas, after you've created an account at Photobucket, go to your page and you should see a button that says something like 'choose files'. Click it and then select the files from your harddrive.
Once you've uploaded the pics you want to Photobucket, click on it to open it and then on the left you should see a box headed 'share this image'. Highlight and Copy (ctrl C) the code in the 'Direct Link' box, then switch windows to your post on here, click the 'insert image' button (looks like a tiny pic of a mountain), then paste (ctrl V) the code in the box that appears. Finish your post and you're done.
Sorry if this is over simplifying it but don't know how much you know about 'puters:thumbup
