For example after the calculation h = 287, s = 0.5, v = 0.34 . Where should I save these values in the image file to convert it to the equiv...
In firefox a broken image appears as just a blank white space. On a white background there is no way to distinguish between no image and a broken image. This makes identifying broken images difficult to recognise and makes them go uncorrected. How do I make it so that broken images produce an X like they do in Internet Explorer? ...

I want to be able to have them dynamically scale down (within reason) based upon the size of the browser. I'm debating the pros/cons of generating these as one of these options: SVG. Great for scaling b...

The error string itself is meaningless as it's...

I have a site setup using transparent PNG images that, of course, don't want in IE without the transparency fix applied. Well, the fix is applied but it still isn't working. div, img { behavior: url('/path/to/fix/iepngfix.htc'); } I know it's loading the HTC file correctly as an alert(1) fires upon page load. The images, however, aren'...
