Danny,
This forum does not allow posting from you harddrive to a message so you need to upload it to a website that hosts images for you.
I personally prefer
www.flickr.com
free and is really user friendly. Allows you to create photoalbums and organize your stuff. Very nice site.
There are tons of other ones as well.
Once you get that setup, each image will have an accesible URL (web address) that you can send people to for viewing of the photo or you can use the method that Optionryder420 mentioned to get it in a forum post here.
Let me know if this confuses more than helps.
