Holland,
When you post a picture you are really just telling the sorftware of the bulletin board where the picture is "hosted" on the internet.
Here is the address of a picture of my Hollis
http://pic10.picturetrail.com/VOL328/1723384/3322151/45306950.jpg

If you were to click on the image box below hwhere you make your posts and paste that address there you would then get a picture of my hollis.

In short you really don't "put" a picture here just the address and the program goes and gets the image when needed.

You need to find a "Hosting Service". There are some free ones. I currently use picturetrail.com. I pay a fee to do this.

Once you have uploaded your picture to the "Hosting Service" you can then get the "address of the picture" to paste in the "image box". You can use the address of my hollis above to practice copying and pasting the address.

I will send you an email with my hosting info so you can practice.
