I've had a few people ask me about this so I thought I'd make an easy to follow tutorial.
Firstly you will need to open an account with
PHOTOBUCKET Or some other image hosting website, although photobucket is the easiest, most user-friendly one that I have found. Upload the image to photobucket ( PB ) that you want to put onto the forum using the onscreen instructions, once the picture is uploaded, click on the ' VIEW ALBUM ' tab at the top of the page and hover your pointer over the picture you want to upload. It will give you a drop down menu with 4 options, LEFT click on the BOTTOM link.
This will automatically store the image's URL address. All you need to do then is to RIGHT click on the forum thread where you want to post the picture and select PASTE and bingo, your picture will now appear on your thread as soon as you click on ' SEND '
This same principal also applies for pictures in your signature.
If you have any further questions then please send me a PM and I'll do my best to help you out
