Map Uploading/Linking

Map Uploading/Linking

I'm hoping to make a request for a terrainer for a map of mine, titled "Twilight Islands", but to do so, I need to be able to link a map from my computer to a post, so if someone could tell me how I would greatly appriciate it.

You can't really link to it when it is on your computer, you needs to upload it somewhere on the Internet.

Darn, I've got a problem there, since I don't personally own a website and if I did I imagine it might look somewhat stupid.
I take it this site doesn't have anything like a storage shed? if not, I'll probably have to upload it as a resource and hope the mods don't mind, 'cause the problem is, were I a mod, I'm not sure I'd let it go there myself, since this particular version isn't meant to be played and really can't. Oh well.
