I have a couple of images that I want to add to a placemark. The problem is when I add the multiple images, google earth displays them one below the other. Is it possible that the image are displayed side by side whenever I click the placemark icon.
And If there a dozen of images for the same placemark can I create a "slideshow" of the imagery that displays only one image at a time and swaps when user clicks the placemark button again?
Any help is appreciated. Thank you.
If you have your images upload to a picasa (google) account you can create a slideshow for each location.
For Example - will only work in Google Earth. http://www.truenorthgis.net/test/digby_nova_scotia.kml will show a slide show in the placemarkers
The code to add this:(only a snippet of full kml)
<Placemark>
<name>Digby, Nova Scotia</name>

You will need to change the flashvar=http://picasaweb.google.com/s/c/bin/slideshow.swf" width="800" height="533" flashvars="host=picasaweb.google.com&hl=en_US&feat=flashalbum&RGB=0x000000&feed=http%3A%2F%2Fpicasaweb.google.com%2Fdata%2Ffeed%2Fapi%2Fuser%2Fstillinorbit%2Falbumid%2F5380434143514463809%3Falt%3Drss%26kind%3Dphoto%26hl%3Den_US
to your own picasa url.

I wanted to do the same thing, I can share with you a solution that worked, but it's very cludgy.
The problem with testingme's answer is that the url of the images is stored in JavaScript and Google Earth will block this content, so I needed a solution that loaded all the images and used only JavaScript no jQuery for scrolling through them.
I copied the horizontal slider code available at dyn-web.com: http://www.dyn-web.com/code/glide-scroll/ then modified it to bring everything in-line so that it could be placed within the tags.
I'm sure this can be optimized (when zipped into kmz this adds 5kb per placemark to the size of the file...) but here is my first pass at it:
