Online Map Plugin

Description:
The plugin lets you see what's happening on the server right from your browser.
Note that this is a beta version and the author's first plugin :) but all the bugs found are being actively fixed; as I can, I'll keep updating this post with newer versions of the plugin.

How to use/install Online Map:

1) Requirements:
- hlds server
- TCP port 1107 must be open on the server!
- sockets2 module (by Bugsy https://forums.alliedmods.net/showthread.php?p=1573388)

2) Setting up the web script:
Download and unpack onlinemap.zip from the attachment, open index.html and edit the line:
window.server = '127.0.0.1';

i.e. enter the IP of your hlds server, for example:
window.server = '85.114.13.88';

Now you can upload the file to your web server and place it wherever you like.
You can also change the TCP port. To do this, use the cvar "sv_onlinemap".

3) Adding minimap images (in English: overviews) (optional)
Take the minimap image you need from the folder root\cstrike\overviews.
Open it with any graphics editor. (Photoshop, Paint.net, etc.)
You can replace the green background with something cooler :)
Now save it as jpeg and upload it to your web server in the folder onlinemap/overviews.
Copy the txt file (<mapname>.txt) to onlinemap/overviews.

Note on the module:
