Hello.
With IE6 and IE7 I have no problem. The thumnails are correctly displayed as follow:
image1 image2 image3 image4 image5
image6 image7 image8 image9 image10
image11
With firefox the thumnails are displayed never in the same way:for exemple
image1 image2
image3 image4 image5
image6
image7 image8 image9
image10 image11
When I click on refresh button of the browser, the thumnails are after correctly displayed in the same way of IE.
image1 image2 image3 image4 image5
image6 image7 image8 image9 image10
image11
I tried a lot of things but I don't succeed to solve this problem
See the exemple in the attached file.
You can also do a test on my online test site
etienne.audfray.com
in the menu "la galerie de photo/les portraits"
Have a nice day.
