This is my preferred method of posting pics. I use a free image hosting site like
photobucket or
ImageShack. Photobucket requires registration, ImageShack doesn't. There are other pic hosting sites that do the same thing, you can search for them. I use photobucket for pics I want to keep track of, use again later and organize into albums. I use ImageShack for pics that I don't care about. Photobucket doesn't allow and will delete pics that have nutdity
The forum has software installed that automatically resizes remotely hosted pics. It's still better if you resize your pics to less than 1000 pixels horizontal resolution before uploading them to a hosting service like imageshack, the pics will then look sharper in the thread without clicking on them. When you click on the pic it will show in full size, then you can also navigate through all the pics in a thread as if it were an album.
Here's a quick video tutorial that shows how to post pics with the hosting method, and following is an explanation of how to do it.

When you upload a pic to one of the hosting sites you will be provided with a few links. You are looking for the direct link to the pic. Select and copy it, then click on the "insert image" icon.
Paste the link into the box and click OK.
All the "insert image" does is place [IMG] in front of the link and [/IMG] at the end of it. This is a code that tells the forum to display it as a pic not a link. You can do the same thing typing it.
If you really don't care about the permanence of a pic in a thread you can avoid the process of downloading it to your computer (if it's from the internet) and uploading again to a hosting site. Right click on any image on a website and select "copy image location". Then you can paste that into the "insert image" box. The problem with this is that if at a later time the website removes or changes the location of the picture your post will no longer show it.
Photobucket provides a link with the [IMG][/IMG] code already attached so you can copy and paste it directly into the post. ImageShack has a problem with showing people the direct link to the image, I don't know why, and makes you go through a couple of steps to get it. You have to click on "show image to friends" to get it.
If anyone finds a good free pic hosting site you can post it on this thread.
