OK, here's my question.......

I take a digital picture.....download off my camera onto the computer.....convert the image to a jpg. (I use Graphic Converter)....then, set the picture aside in a file of my choice.

When I went to add the image in a message, a window popped up asking for the image's "URL"
address.

My question is how do I create a "URL" address?
for the image?

Thanks in advance for any help.
