If you are unsure as to how to do that, follow these simple instructions:
1/Host a picture at one of the various online free pic hosting sites, I personally use Photobucket but there are several you can use such as Webshots or flickr
All of these allow you to store pictures online so that they can be linked into emails, Instant Messenger conversations or bulletin boards/forums such as this.
2.Once your picture is hosted, follow the instructions on the site to copy the URL for the picture. (the URL is the 'address' of where the picture is to be found on the internet, it tells the net-hamsters that work your browser where to find it. Its the bit that starts http in the bar at the top of your browser window).
3.You can either post the URL as a link:
http://i27.photobucket.com/albums/c164/ ... 123/a1.jpg
To do that, use the URL button which you can find underneath the subject bar, on the far right hand side, click it once, put the URL in immediately after the tag, then click it again to close the tags.
Or you can put the image right into the post. Please only do this with your own images hosted on a suitable site, hotlinking to images hosted on other peoples sites without their permission is 'rude' as it can hog their bandwidth.
4.Choose a picture that isnt giant, and wont distort the forum view, or ill have to put my mod hat on and go and edit it to a link for you.

To do that, again copy the URL from wherever the picture is hosted, then click on the Img button (next to the URL button), paste in your link and close the tags by clicking the Img button again.
5.Then cross your fingers and hopefully the faeries of the internet will have posted your picture up here!
So if this has worked, you should have a link to my little lurcher Dill, and a photo of my big saluki x Abby. Edit; there is no picture of Dilly if you follow that link because the picture has 'moved house' and theres no one home at the address in the link any more. This happened because after i posted this thread I moved that photo to somewhere else with a different address/URL.
