The only object in there that has anything to do with the JS engine is the Date
object....
Is there a live testcase somewhere?

Reassigning to Browser-General for now. I notice the use of the
getTime() method above. We've been having crashes on that on the
Windows OS, but not on Mac, AFAIK.
See bug 160602 for details on that:
"Large integers, e.g. getTime(), causing crash at 0x39393929"
gsa@myrealbox.com:
1. What do you mean by the "javascript code does not work".
Are you crashing? Does the image fail to refresh? What?
2. Are you getting any errors in Tools > Web Development > JavaScript Console?
(be sure to clear it of any previous errors first)
3. Be sure to check your settings in Edit > Preferences > Privacy > Images,
and Edit > Preferences > Advanced > Scripts & Plugins. Do you have any
setting that would affect this code. In Scripts & Plugins, do you have
the box "Allow scripts ... to change images" checked ?

I believe this bug is INVALID.
getTime() returns a long integer. Reporter, are you sure your images
are named correctly?

> allow javascript to change images is deactivated
As in the checkbox is not checked? Then how do you expect this to work?

I'm reading the reply in Comment 3 just as bz is.
Reporter, is the box next to "allow javascript to change images" checked or not
checked? (and please use the term checked)
tested on webcam site it works with scripts & plugins turned on
