app engine about jquery-rotate HOT 4 OPEN

some additional information:
My browser is firefox3.5, the image appears well in the browser (so it is well 
served
by app engine) but when calling:
$("#img").rotateLeft();
I get the above error.

I try the solution given in
http://code.google.com/p/jquery-rotate/issues/detail?id=3
it allows to rotate once, but calling again:
$("#img").rotateLeft();
makes it disappear...
seems it is the way to follow !

See issue 11 for a resolution that works for multiple rotations

I solved this old problem checking why my img was not cached: it was because 
they
were served through a poor redirection.
Once solved this cache problem, no more issue to rotate img.
