A lot of members like to use ImageCave...and here's an explanation of how to upload pictures from beginning to end:
How do I post a picture?
There is no current protocol for uploading images directly to this board. Therefore, you must create a link to an image stored on a publicly accessible web server, e.g. http://www.some-unknown-place.net/my-pictu
re.gif. You cannot link to pictures stored on your own PC (unless it is a publicly accessible server), nor to images stored behind authentication mechanisms such as Hotmail or Yahoo mailboxes, password-protected sites, etc. To display the image, use either the BBCode [img] tag or appropriate HTML.
1. Create a free account with www.Imagecave.Com or another publicly-accessible, picture hosting web server.
2. Create an album.
3. Add pictures to the album.
4. Upload pictures.
5. Modify picture size.
6. Copy the "ezcode" from the picture and paste it into your post.
