Matt, you CANNOT post pictures here. But you can link to other pictures already up on the web using this nifty html code:

First, you need the URL (e.g. http://www.artnetgallery.com/graphics/art/roberto_matta/ComiqueTrippe.jpg) of where the picture is located. This can be found in the "properties" when you right-click on the picture. Then you put that URL into the following section of code, in between the quotation marks, as the image source, abbreviated "src."

<img src="http://www.artnetgallery.com/graphics/art/roberto_matta/ComiqueTrippe.jpg">

And the output of that line looks like this when published.
