First off, welcome to the Guild wdmartin! Second, nice job on the map. I think you might be able to find a better texture for the roofs though (this one is a bit of an eye sore). As to your question, it's generally best to upload a picture via the attachment system. In fact, your post was caught up in the moderation queue because, as a new member, you had several links in your post, which sometimes is an indication of spam. It's been moderated now and should be visible to everyone.
