I have modified the settings of the attachment system...I think I figured out what the problem was...

The file size limit of 5Mb should now be properly in effect for images. The system was limiting images to 640x480...no longer is that the case. Please try to upload your maps again in large sizes (up to 5Mb).

If you have a special case that needs greater than 5Mb please let me know.

After I determine whether or not its possible, I will change the policy to allow Industry Pro's to upload larger files.
