go to
http://www.photobucket.com/ set up an account
sign in, then load your picture by clicking the 'browse' button
your picture files will then pop up, you select your picture then click 'open'
fill out the discription of the picture if you want to, id reccoment clicking the box 'keep origional picture names' to unselect it because some cameras just number the pictures so each time you load the pictures on your computer itll start off with "picture 1" and then you wont have to worry about renaming the pictures...
then click submit and your picture will load
once it loads it will show a thumbnail, a URL code, an IMG code, and a TAG code.
coondawgs uses the IMG code so you just copy that code by holding down the left click button on your mouse and highlighting the entire code and then right clicking the highlighted code and selecting "copy"
then go to your thread, click relpy (or new post depending on which your doing) and then paste the IMG code in the text box by right clicking again and selecting "paste"
you dont need to push the Img tag at the top of this page because photo bucket already includes [img]"code"[/img] in it.
