Custom Location Icons

The ability to upload custom icons has been added to the edit location page.

I live in Europe and would love to add some of our stores and stuff plus my work office logo.

Great idea - there's a fairly tiny selection of US-stores just now, would be nice to be able to add some ones for other countries too, if we could add them ourselves that would be great.

And support uploading of custom icons so we don't have to hotlink somewhere else.
