Or you could FTP (upload) the picture file to your ISP's server if they give you some hard drive space. Most ISPs offers this, but not all. Then you can use the IMG tag to display pictures inline. More of a hassle compared to Webshots, but you do get to display them in your posts.
Or, just attach it to the post. Most times you have to resize them dimensionally and for file size, but Microsoft offers a free set of utilities called TweakUI. In it is a tool called Resizer. Takes about 8 seconds to get any size picture ready for a DRN post attachment.
EDIT: I switched to Ekko Expanded, and still could not see it. You probably were able to see if because Webshots had not started denying the referenced link. I thought I was going nuts at first, but finally pinned Webshots down, and they admitted that this is what they do. Cuts down on the load to their servers.
BTW, that is a sweet setup. What are you going with for brush guards? Once you get into slicing and threading through the trees, you're going to love it!
