Hello, I have two problems with the masonry gallery.
The website is: http://www.berraldacci.fr
First problem: when loading a gallery in IE7, some images are missing

If the page is loaded again (without cleaning caches), all the images are displayed (4 more):

Same problem in Safari 6 (4 pictures missing):

If the page is loaded again (without cleaning caches), all the images are displayed:

Second probem: when loading a gallery in Safari 5/6 or Chrome, a gap appears between two rows

If the page is loaded again (without cleaning caches), there is no gap.
As I've customised the theme, I've set up a new installation only for test (last version of wordpress and unmodified flashlight theme) :
Clean install
Unfortunately, the same bugs occurs…
Here you can see a screencast of the "gap" bug in Chrome :

And here a variant of the bug in Firefox :
Overlap bug in Firefox 3.6.6
Thank you for your help.
