This is not a question, this is a tutorial.
How Do I Post Images.You need to use a web host such as,
Photobucket. Then enter the image code. Done!
Why Do I Need To Know This?So we dont get any more HOW2POST PIX?!?!?! topics. It is getting annoying reading idiotic topics about people who are unable to use an image host.
How Do I Make Transparent Stuff?You need to get
Paint.Net. Once you find a picture you like, resize it to about 75x75 at the max. Then delete what you want. It must be saved as a .gif or .png to become transparent. If the dimensions are too big, it will be converted into a .jpeg type picture and have an ugly background.
A Picture Posting Equation.You need a link from the picture (copy picture location) and insert it into the image code.

By hitting that button, you can paste the link into the middle of the code.
Enjoy your Pictures!
