Heganoo looks like a very nice and easy online map-making site. After a quick registration (though I never received a confirmation email, but was still able to use the site without it) you can identify any location or locations on a map and make it a point-of-interest where you can add text, links and, most importantly as far as I’m concerned, an image by just pasting its url address. That ability to add an image via web address is a bit unusual for map-making sites.
I’m adding it to The Best Map-Making Sites On The Web.
