<img> firefox return this exception (after first image loaded): 

[Exception... "Component returned failure code: 0x80040111
(NS_ERROR_NOT_AVAILABLE) [nsIDOMCanvasRenderingContext2D.drawImage]"
nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)" location: "JS frame ::
/jquery/jquery.rotate.1-1.js :: anonymous :: line 51" data: no]
[Break on this error] 

LINE 51:
context.drawImage(canvas.oImage, 0, 0, canvas.oImage.width,
canvas.oImage.height);

When i reload the page 3 image are show, the next reload 5 image, the next
reload 8 image, ... and finaly all image are show.

This is indeed a bug with jquery rotate and firefox, I suggest the dev changes 
the
script to what I suggest below.

The problem is that, in firefox only, if the image hasn't been cached, it 
doesn't
seem to rotate the images, AT ALL! No matter if you add a delay, or even do it 
using
a function in the "onload" attribute of the image.

After many hours, I came up with a solution.

At the moment line 30 onwards looks like this:

canvas.oImage = new Image();
canvas.oImage.src = p.src;

etc.

Add two lines inbetween this two looking like this:

canvas.oImage.onload = function() {
}

Then move the code from:

canvas.style.width = canvas.width = Math.abs(costheta*canvas.oImage.width) +
Math.abs(sintheta*canvas.oImage.height);

to:

context.restore();

into this function. This ensures images are properly loaded. I imagine this is 
a bug
with firefox / canvas. I was preloading the image before running the rotation, 
but
the canvas seems to ignore that. I'd consider this a pretty major problem. 
Anyone
visiting my site on firefox for the first time would not see any rotated images 
and
because of the error a lot of other JS didn't work.

I've attached the updated jquery rotate too. Enjoy!

Hi,

I tried your jquery.rotate.js and the first rotation is working fine. But when I
rotate the canvas image, the canvas is empty, and the image is gone away.

any ideas why?

Hi,

Your solution made the trick for me. I have 12 images rotated on the load of 
the page.

If only one image ratated you should check your javascript errors.

Thanks,

See issue 11 which solves the multiple rotation issue as well
