How to Host/Post Pictures
You will need a hosting service that allows remote hosting!  Remote hosting means that you can see the image when it's posted somewhere other than the site it's uploaded to.  Some examples of sites that do not allow remote hosting is Yahoo Photos, Tripod, iVillage. 

In most cases, your ISP will give you remote hosting space.  Check with them before signing up for hosting elsewhere.

Some sites that are free or cheap that allow remote hosting:

Image Magician --Easy to use and reasonably priced. 
Currently not accepting new members, and they are not free. 

walagata  --Haven't tried it, but they give you quite a bit of free space.

Ranchoweb --Also reasonably priced but not as user friendly...still very reliable.

Photobucket --Free and allows animated gifs.  To keep this up and running, please consider making a donation!

villagephotos --Free for 5MB and very reasonably priced for larger accounts.

Boomspeed  --No longer free.  To be honest, this would be my last choice for that price.

Lycos --Free, but you have to create a webpage to use it.
 

HTML Code for posting:
1. Save pic to hard drive.
2. Upload to hosting service.
3. Get URL for pic you uploaded
4. Post the URL in the appropriate place in this code:

<img src=http://www.urlgoeshere.jpg>

5. Post that exact where you want to display your picture.

You're done!

You can also size an image smaller. If the original, for example, is 400x500, and you don't wish to resize the original, but would like to display the image smaller, you would use this code:

<img src=http://www.urlgoeshere.jpg width="200" height="300">
