Nice video, SW!
BTW, for anyone who doesn't want to establish an account with an image-hosting service, there are several who will let you upload anonymously. For example:
ImageShack or
PostImage.org. (This is not an endorsement, just a couple of services I've run into.) Or, if you have your own website, you can host the image yourself.
To post an image manually, just click the Insert Image

button, and put the URL of your image between the tags, like so:
[img]http://www.example.com/myimage.jpg[/img]
Advanced image posting with thumbnails:With many image-hosting services, this isn't very advanced at all. The service will automatically generate a thumbnail of your image, and the correct code to insert it in a post.
If you want to do this manually, here's how:
First, make a thumbnail (miniature version) of your image, using your favorite software (Photoshop, GIMP, etc), save it under a different name, and upload it (along with the original) to your image-hosting service or web server.
Here's my original image:
http://statler.ws/RosaFoetida1.jpgAnd my thumbnail:
http://statler.ws/RosaFoetida1t.jpgClick the Insert Hyperlink

button and then the Insert Image

button:
[url][img][/img][/url]
Following the first
url, insert an equals sign and the URL of your
original image:
[url=http://statler.ws/RosaFoetida1.jpg][img][/img][/url]
Then, between the
img tags, insert the URL of your
thumbnail image:
[url=http://statler.ws/RosaFoetida1.jpg][img]http://statler.ws/RosaFoetida1t.jpg[/img][/url]
You're done! Here's the result -- a thumbnail which is a clickable link to the full-size original:

If your original image is large, using thumbnails will be a help to forum members with slow Internet connections. It will also decrease the load on whatever server is hosting your images.
