The last picture in alien's post is here:
http://icanhascheezburger.files.word...r-his-date.jpg
What he's doing is using the 'Insert a Picture' button (the one that looks like a mountain with a moon over it) and then inserting the URL for the 'icanhascheezburger' site where that picture is hosted.
All I did was upload the picture to one of the many image hosts that are available and then link to it there.
The problem with this approach (and with alien's) is that we don't control the servers that the images are on. If they have a cull, go down, or block hotlinking, then the image in the post will disapear as well.

Oh,and I've removed the link behind my picture now - as you can see, it's no longer clickable but the picture remains.
Next time you get a picture you want to post and I'm online drop me a PM and I'll talk you through posting it if you like?
