From the
TB rules/FAQ/CUP page...
"There are two ways to add a picture to your post. The first and best way, is an available option when the image is already on the web somewhere. If this is the case, grab the URL of the image (in most browsers, right-click on the image, then "copy image location"). Then, in your post, paste in that URL, and wrap it with tags. So for example:
L/bracket 'img' R/bracket [url]http://www.somesite.com/someimage.jpg[/url] L/bracket '/img' R/bracket*
This will display your image "in-line" - that is, it will appear full size, in your post exactly where you put the URL.
The second method is to upload image attachments to your post. This takes up space in your attachment quota (which is larger for Supporting Members), and the images will appear as small thumbnails beneath your post. A user can click the thumbnails to get the full size version.
To upload an attachment to your post, below where you type your post text there is an optioned labled "manage attachments". Follow the instructions there to upload your images. Note the size (filesize and dimension size) restrictions on uploaded images.
Given the fact that there is no size restriction on 'linked' images vs 'uploaded' images, and given that linked images appear full size in the post, this is the preferred method of including pictures in your post. There are websites out there like PhotoBucket.com which will host your images for you at no cost."

* I had to replace the actual bracket with a poorly-written description...it wouldn't show otherwise.
L/bracket = [
R/bracket = ]
And now it's showing a fake address...this is getting better by the minute. Follow the link I posted in the first line and look for the 2nd question under 'TB most asked questions' to see what it's supposed to look like.
