That sucks! You have to pay to be able to post pictures?!
No, that's not right. You can post them one at a time by attaching them to your message. Alternatively, you can host your own pictures on the web space your ISP gives you and post links to them. The second method allows you to use the IMG tags in your posts and include a whole bunch of pictures in one message. It's way easier and faster to post pictures that way if you have a bunch of them.
Smugmug and the like, however, are convenient and at $20 a year not exactly expensive.
