In my tutorial on adding custom icons to My Places in Google Maps, I mentioned that you can't use Dropbox to host your icons. That's because it requires a log-in. Hex Central reader Jamie Barber wrote to say that you can indeed use Dropbox for this purpose, provided you place the relevant files in your Public Folder. I have amended the article accordingly.
Once you've uploaded your icon file to your Public Folder in Dropbox, all you have to do is right-click on the filename, and select Copy Public Link (see screen shot). The file's URL will appear in a pop-up box, from where you can copy it to the clipboard. If you prefer a shorter - but more cryptic - version of the URL, click on "Shorten link".
You can then go ahead and paste the link into the Placemark Editor, as I described in the article.
There's one other update to the article. When I first wrote it, custom icons didn't show up properly in printed versions of a My Places map. Google has now fixed this problem. Now, when you print your map, all the icons will appear as expected.
