Putting pics in your post is de rigeur, but unfortunately I have to pay for the ability to offer uploads. Host your pictures at your favorite hosting site.

Here's some links to popular ones:

Flickr

Photobucket

Tinypic

[edit] I actually can enable attachments, but I have to pay to get more than 20 MB of storage, so seeing as I want to keep costs minimal I won't be allowing attachments for the time being.
