•Re: Image2HTML

You're doing far too much work for most of this. See how I did the task in my column. ImageToBlob means you don't have to fetch each pixel. A single sprintf to get the colors to hex. And your scaling can be drastically reduced... by default, if you say "resize to 50x50", you get a proportionate scaledown that makes the largest dimension 50 but the smaller dimension appropriate! No math required.

The fact that I did it that way was that I was trying to do it with GD first, then realised that it's not installed on the test server, and I needed to put a live version, so I switched to Image::Magick, which is the first time I use. So `$image->GetPixel($x, $y)` became `$image->Get("pixel[$x,$y]")`. And besides, the documentation of Image::Magick is still a bit greek to me. Thanks for the advice.
