This has been asked loads of time, we probably should do a step by step guide and make it sticky somewhere.
Right, here goes, you need to get some web space to upload your pictures too, a good one is
www.photobucket.com Sign up to create an account and upload pics from your pc to your photobucket account. Once you've done this there will be three text fields below your pic in photobucket, copy and paste the last one that has IMG tags in it and put it in your posts and it will show the pics. Basically you need to put the photo url between some img tags which appear when you click this button on a reply
. e.g [ img]www.picsofmycar.co.uk[ /img] There is no space after the "[" by the way but if I left it in it would try to display my nonsense URL. Apologies if I've confused.
