Wavelet Image Compression Library 3.0

So I don’t know anything about Dan Volmer’s wavelet library, but since he’s up to release 3.0, I guess I ought to at least look into it a bit. Here’s what he has to say about it:
It is a fairly simple but thus compact (executable with compression and decompressing is 30kb uncompressed) and relatively speedy image compression library, that provides up to 16 channels per file and combines lossless with lossy compression in a single algorithm, that can even be changed from channel to channel. As it’s based on the wavelet transform, it allows for progressive decoding (which means that if you only have the beginning of the file, you get a lower quality version of the whole file) and can also extract smaller “thumbnails” of the original image.
