Super Map Icon Maker + Automatic Server/Client Synchronization

This addon allows you to semi-automate making map icons and send Map Icons to Clients. This means you won't have to make additional addons containing all the missing map icons.
It automatically detects all maps that don't have an icon yet either through themselves or additional addons. By executing a console command it takes a .PNG screenshot at your current position, names it after the map and saves it under /data/mapicon/../maps/thumb. After one second it switches to the next map that doesn't have an icon yet.
When you're done you can copy the /data/mapicon/../maps/thumb folder and paste it into your map icons addon to upload it to the workshop or you upload it to your server's /data/mapicon folder and have it be sent to all connecting clients.
Also, the addon cleans after itself. As soon as your icons addon is updated and contains the new map icons this addon will delete all the .PNGs that are now included in it.

This is a very easy way of making map icons to avoid having blank images during mapvotes.

Your screenshots are saved in your /data/mapicon/../maps/thumb/ folder on default. In order to send them to your server you can open up the GUI, search for your previews and click on the upload button.
Alternative: just copy them to /data/mapicon/ and use the console command mapicon_pushMapIconsToServer.

Copy your made screenshots into garrysmod/maps folder and restart your game. Your main menu should have a map.thumbnail for all maps now.

This addon will be reworked soon and receive a fancy new GUI.
