First of all, you need to get your image onto the web.
You can either use an uploader.
http://www.photobucket.com or if you have web space, upload it there. Note. Some sites do not allow remote linking of images. i.e Tripod sites.
Once the image is on the web, you need to link to it from here.
This is done by using the IMG tags.
The easiest way to do this is as follows:
First of all upload your image. If you use Photobucket, select and highlight the URL in the link box. Copy this ( CTRL + C ).
Go to the thread on here you want to put the image in, start your message and at the point you want the image Paste the image ( CTRL + V). Then select and highlight the URL in the message ( the link you just pasted ) and click the
Img button at the top of the page. ( Not available on on Quick Reply ) This ads the img tags at the beginning and end of the url. ( See below )
Using the tag and url below will display the following image.
This also works for Signatures.
Just remember, try and keep images to a 'reasonable' size as large images in posts and signatures can become a pain to users of the messageboard who have a slow net connection or a low screen resolution.
