This did not work for me. Let me give a few details.
I am using the scripts from MacOSXHints to take a picture on wake from sleep and post to a web page.

This was working fine, but somewhere around the end of March this stopped working (perhaps when Apple issued an update?). The symptoms are that on wake from sleep, the light on my iSight goes on for a short while as it should, indicating it is taking a picture. But no picture is saved. When I use the Activity monitor, I see that the program iSightCapture is still running. It looks like it gets stuck after taking the picture. So, rather than not being able to access the iSight camera, it looks like something gets stuck after taking the picture.
I tried the work around from this article (I'm running Mac OS 10.4.11). I created the script application as directed, and when I double click on it, it works fine. But, when I put the path to the script application in my .wakeup file, I continue to get the same behavior - on wakeup, the camera light goes on for a short while, but the iSightCapture program never exits and no picture is saved.
By the way, one consequence of this problem is that Skype and other programs can not access the iSight program. The stuck iSightCapture program continues to hold exclusive access to the camera until I reboot the computer or kill the process. This is what originally led me to investigate the issue.
