When you zoom in or out an image, not a page, only an image, like www.yoursite.com/logo.jpg if you are zooming in, in one zoom it zooms out. If you are zooming out, in one zoom it zooms in.

It happened to me in the url provided, but i doubt it will be accesible in the future.

Reproducible: Sometimes

Steps to Reproduce:
1.Go to url (or other image, not all of them reproduce this bug)
2.Zoom out (ctrl + -) it zooms out
3.Zoom out (ctrl + -) it zooms out
4.Zoom out (ctrl + -) it zooms out
5.Zoom out (ctrl + -) it zooms in
6.Zoom out (ctrl + -) it zooms out again

Actual Results:  
In the image provided it happened what is described in the steps, in other images i've tried to reproduce it didnt

Expected Results:  
Zoom out every time

This image was sended through an IM software that uploaded it atomatically to that location an then send the link to the other person

Reproduced with http://www.mamopedia.pl/userfiles/A/noweeeeeeeeeeee/banan-1.jpg.
Mozilla/5.0 (X11; U; Linux i686 (x86_64); en-US; rv:1.9.2.17) Gecko/20110420 Firefox/3.6.17

The bug seems to be always reproducible if I just start Firefox, open the image and do the zoom thing. But if I play around with it a little bit the bug sometimes disappear - and then suddenly reappears again.

Bug 633768 describes a similar image zoom behavior (but in an iframe) and that has also been triggered by af032ca9e9ec.

Maybe this bug should get duplicated against bug 633768.

Indeed.  This is the same issue.
