which is an unknown url
$r = ($rgb >> 16) & 0xFF;, which makes it think the php code already stops

Sorry
First: instead of "JPEG img URL: " that is showed at 1 px per char I suggest to put the following code:
Second: change the input type in "file" so you get a browse button as well.
That's it !
Thanks again
[input type="submit" value=" JPEG img URL " disabled]
Nice code otherwise!
I have been thinking about doing a script like this forever :)
Great for smaller files.
Too bad it takes so long to render, otherwise could do some cool javascript enlarging / reducing the image.
I bet CSS 3 could do some cool stuff with this as well, doing gradual color fades etc.
