nope. . .
two problems,
first you must use html to post images, which can be found by clicking hte info button on the sidebar
second you need a the picture to be somewhere on the internet, the picture you just tried to post in on your computer. . . if you want to post pictures sometime syou can email me and ask me to host thaem and I will give you the location and you can post it with that. . .
hope this helps!
