use your mouse, right click the picture, then select "copy"
Then open up paint, every pc has it, and right click again, and choose "paste"
Then pick you favorite color and drawing tool, circle, then goto file, choose save as, save to desktop as whatever name you want. Then use a free service like photobucket, or any of the others out there, register, and upload the photo. Then use the link provided, and post it here on the planet for us to see
Usually from a site like photobucket, when posting, it will contain the following line of script. [img] your link here, no spaces [ /img] Keep in mind, NO spaces, all back to back. Hope that helps...
