As the other members have said....
using a site like Photobucket is the easiest way to post photos...
Below is a little more detail.http://photobucket.com/
It very user-friendly, and best of all, free!
Once you register there, you can start uploading pictures to your albums there. When you upload a picture, make sure it is no bigger than 640 pixels wide...there is an uploading option on Photobucket that will upload them to that size, or whichever size you choose.
When you upload a picture, you will see it in your album. Below each picture are a set of codes. To make a picture appear within the body of your post, you right click and copy in the code that has the tags that look like this: [IMG].
When you submit your post, the picture will be there.
I look forward to seeing your pictues.
