The last time I used My_eGallery, it has the option for the user to upload the image for the map and then they have to send you the map file. You rename the map file to match the Screenshot filename and then upload it to the same dir. as the Screenshot. Then the screenshot will have th eMap zip associated with it as a download link.

Coolmap.zip

The other option was to have my users upload the screenshot and map in a zip package, then I would unzip it and submit the screenie for them and then just upload the zip myself via FTP.
It was rather tedious now that I think about it.
