It works fine for me too ! Thank's very much Antoine!

Works fine now. Great job Antoine!

And I also added the frame on the picture preview of the edit-vehicle page: now you see where on the picture the frame will come, it will be much easier than doing try-view-edit-etc.
Only "limitation" currently is that to move the frame you have to click on it to hide it, then reclick on it to make it visible again (I can't correctly catch the click on the frame instead of the picture)

Should be fixed in IE 6 now, I hope that it still works in all others (tested: IE 6 & 8, Firefox 3.5, Google Chrome 2, Opera 9.64, Safari 4)
I had to use another system, relying on Javascript instead of CSS

I now use FireFox. Works fine.

Good
And indeed I still haven't fixed it for IE 6. I hope to have time to search for a solution this weekend.
But if you applied updates to your windows (yellow icon in bottom right corner) you would get IE 7 or 8 at the same time

Still not operating correctly for me, though, as you've seen , I use it for new pictures I upload.

Confirmed! thanks a lot Antoine

UPDATE :
fixed in IE 7 & Opera 9.6
if people who had problems with these browsers could check and confirm that it is fixed for them?

So now it should work fine for edit page (click on the pic) for all web browsers (IE 6, 7, 8, Opera, Firefox)

But the display of the frame on the picture still fails on IE 6 due to a space between car title & car picture... I hope to solve that.

Just tested it for admins and visitors on Mac. Works fine with Safari 4 and Firefox 3.
