First, you need to save your pictures online somewhere, for example, at Photobucket or Flickr. I use Photobucket. This involves creating an account (free), and then uploading your pictures from your computer.
Now, you go to your very own Photobucket page, and you'll see a screen like this:
Below the picture you want to upload, click on and copy the text next to the word "IMG Code."
Then, here at the forum, simply paste that line of code into your message where you want the picture. It will look like this, without the spaces in the brackets:
[ IMG ]http://i57.photobucket.com/albums/g229/Quossum/BoardUse/Howtouploadpictures.jpg[ /IMG ]
I like to click on "Preview Post" just to make sure things worked out well.
And there you have it!
Ask away if you have any more questions or need something explained more...I'll do anything to get to see more Poodle pics!
