    Shroom Image Set

    Accidentally I found a huge collection of images related to mycology. There are more than 300 thousands images of fungi. Mostly in JPEG format but there are about 800 images in TIFF (uncompressed and LZW).
    I ripped all of the tiffs, removed duplicates and similar photos, selected 26 files and converted them to 24bit PNM format. There are both naturalistic and kinda abstract, microscope driven photos.
    26 files, 253 466 520 bytes.
    So if you want to have another image set to play with - you're welcome to download it.

    In case you want to dig the whole collection please visit the http://images.digitalmycology.com/orig/ link.
    Please be patient because due the limited speed of server it can take a couple of minutes to completely load the list

    Thanks for testing but your results can be interpreted as bias since you excluded some files from testing.
    The real results on full set:
    Code:
    bmf 2.01 -s -q9       76 970 604
    gralic 1.11d          78 213 158
