you can upload it in the fan submission or with html

Just do a search on the forum you will find one that tells you how there are many topics on this

they should have a stick thread to show how to put images.

OK. To post pics in the regular forum such as what this is, this thread should help you find what you need.

To post pics as actual 'fan art' to get rated on, go here.

When I right-click and choose Properties, it doesn't have "Address (URL)". How can I still post it?

Do you have it posted or saved somewhere on the net or is it saved on your PC? If you want to post an original sig or images within the text of a post you need to have it somewhere on the net. I have all my sprite komics and avatars saved on a free angelfire account.

You might be able to upload a pic from you PC through the Fan Art Submission page here, I'm not sure. *shrugs* Never done so myself, since none of my work is actual drawings,paintings, etc but ripped sprites that have been re-arranged.
