Yes, if you attach the picture, it has to be less than a certain size (60000kb or something like that). If you have picture software, just resize the picture until it accepts it.

Otherwise you can post the picture of the web somewhere. When it's on the web, right click on it, click on properties, then copy the address. Then when you're typing your post, click on the IMG above the typing area and paste the address of the picture. If you have your own website this should work, but if you're using certain photo pages it might not. The one we've found that works....so far...is Image Station

There have been many posts on this, so if you need more help you can either just ask, or do a search for posting pictures. I seem to remember Phred (I think) wrote up a good description of how to do it awhile ago.

Hope this helps because we love pictures around here!
