Phototonic is a fast and functional image viewer and organizer, inspired
by the traditional image viewer design (i.e. thumbnails and viewer
layouts).
Pixelize works by splitting up the image you want rendered (or duplicated)
into a grid of small rectangular areas. Each area is analyzed, and replaced
with an image chosen from a large database of images. Pixelize tries to pick
images that best match each area.
Pixelize works best when it can choose images from a very large database of
images. With about 1000 images, Pixelize can do a reasonable job.
Picpuz is a free Linux "jigsaw puzzle" program.
You can take almost any image (jpeg, tiff, png ...)
and scramble it into many pieces (tens to hundreds).
You can then reassemble the picture using the mouse to move the pieces around.
PikoPixel is a free application for drawing & editing pixel-art images, originally for Mac OS X.

Pinpoint a simple presentation tool that hopes to avoid audience death

pngcrush reads in a PNG image, and writes it out again, with the
optimum filter_type and zlib_level. It uses brute force (trying
filter_type none, and libpng adaptive filtering, with compression
levels 3 and 9). It does the most time-consuming method last in case
it turns out to be the best. Optionally, it can remove unwanted
chunks or add gAMA and sRGB chunks.
A library of image understanding-related algorithms.
Provides basic image processing, mathematical morphology,
and machine learning algorithms.
Pngrewrite is command-line utility that reduces the unnecessarily large palettes
that some programs write into PNG files. It also optimizes transparency data,
and reduces the bits-per-pixel if possible. Handy for post-processing PNG files
before putting them on a web site.
ppminfo shows details of an ppm-file on the console. It seems this is
the only utility missing from netpbm.
