As demonstrated in the attached file, the images are meant to "grow" as and when they're loaded. This works as expected in Firefox and Chrome, but not in Safari 4. The commented out line, however, works in all three browsers as expected.
It's the same case when the images are made to "fade" in (doesn't work in Safari, works in Firefox and Chrome), if that helps.

Testcase for bug.
Okay, correction: the bug is not consistent. I'll try to come up with a more consistent test case if I can, while someone reviews this.
How are you animating the images? The testcase is not simple enough.
[I hope that's the answer you were looking for?]
