Ok, I have a problem. Maybe someone can explain to me. I just took some pictures on a digital camera (of our new tatooes) and then I tried to post them on my journal with the insert image thingy. But its not working, I have tried several diff ways, and cant figure it out. The problem is that I have it saved on the comp as a JPEG, but the image link asks for a URL address. So, how do you get around this?
SOMEONE PLEASE EXPLAIN.
