Easiest way to be able to post pix's is to set up a homepage on the DIS, then using any photo software, prepare the photos, making them a decent size so they won't be too big, etc, saving them as jpg files, download them to your new homepage, then from the homepage get the url address the photo was assigned.
Then just post your messages here on the DIS and put in a link to the photo.
Your homepage doesn't have to be a 'real' homepage, it can just be a place that stores your photos. Once you get it set up the first time, you can add photos with ease.
If you send me an e-mail with a sample photo, I can look at it and also give you exact directions on how to set everything up.
