To put a pic in, first you have to have them uploaded at a website that allows imagehosting. The best one (that I know of is) Imagestation... http://www.imagestation.com Get an account there, upload some pics.

When you have the pics uploaded, open a pic. Right click on it, and go to properties. There will be a URL there. Highlight the URL and copy it.

In the post here click on the IMG button (above) and paste that url.

To change the color there is some options above the reply...the same place as the IMG button, you can choose size, font, color, etc.
