It's possible to place a object inside inside of the marker in the Map, like a photo of flickr.

<a href=http://www.flickr.com/photos/pcompernolle/277663326 target=_blank ><img src=http://static.flickr.com/79/277663326_3116bfa37c.jpg?v=0  width=250 height=167 /></a>

Don't place (double) quotes in the text. If you need a space in the linkTitle use "& nbsp;"

If somebody has a great plugin to show flickr photo's with full capability's (like notes in pics) please send me an email.
