Very nice! Please consider using the forum's image attachments function for your images, though. That will create a thumbnail for the image and prevent it from stretching the viewport. Also, if something weird happens at Photobucket, the images will still be viewable here.
You can make the attachment by supplying the Photobucket link, so you don't have to upload a large image twice.
edit: Do you have a version without the grid? MapTool makes its own, and some people play with no grid, or with hex grids.
