Possible Error in HTML5 Canvas Example

[Guest elispene]

Not quit sure where to post this and there doesn't appear to be any contact information on the W3Schools main site...Anyhow, I think there is an error in one of the canvas example where an image is being dawn onto a canvas (link).If you are already on the page with the list of examples, you may notice that the last example actually shows up as a blank canvas but when you go into the actual example the image shows up. From here, if you got back to the previous page (Back button, Alt + left arrow, whichever...) then the image would show up.Moreover, I tried copying the code (and the image, of course) onto my machine and then run it - nothing. After fiddling around a little and Googling for a bit there seems to be a pre-loading problem with the example on W3Schools.One solution I have found so far is to add, after the lines:var img = new Image();img.src = "img_flwr.png"The lines:img.onload = function(){ context.drawImage(img, 0, 0);}Apologies in advance if I made a mistake - beginner here. :)Oh, also, because of that an animation example that I was working on didn't quite work out for me - feel free to drop a hint or two.
