Cloned block image zoom problem

[MJW]

I have cloned the standard Webcam block to be able to load multiple images in several other blocks. After setting unique block names, etc. everything works except when I click on certain images, the image is not zoomed out like in the standard Webcam block. If you go to my site, weather.westfamilynj.net/meteo, you can see my WeatherUnderground maps. Each is supposed to zoom out when clicked, but they don't. If you click on the webcams, or the lightning map, they do zoom out. Can any one look at my blocknameBlock.php files and figure out where I went wrong with the editing/conversion? The three that don't work and one that does work are in "http://www.westfamilynj.net/Files/blockfiles.zip".

thx

Mike
