You have to restart Pd for GEM to notice the new plugins.  If you did that already, maybe there is a conflict between self-compiled Pd GEM and system-installed Pd GEM?  Please send more information:

$ which pd                                     # should be /usr/bin/pd
$ pd -stderr -verbose your-patch.pd 2>log.txt  # attach log.txt to mail

thanks claude, I installed it by "sudo apt-get install gem-plugin-magick",
but it still can't load PNG. Pd says same as before: only "Image loading
support: SGI jpeg". how to solve it?

thanks,
jonghyun

on ubuntu 14.04 linux, [pix_image] handles only JPEG files. No PNG, No
others. How to load PNG or TIFF files? when I make [pix_image], Pd says
"Image loading support: SGI jpeg"

FYI, on Mac OS X, it handles PNG files, but on linux doesn't. Why
linux can't do that?

Linux can do that, don't worry.  GEM uses a plugin system for image
loaders/savers - probably GEM is distributed with them split out into
multiple packages. Try:

$ aptitude search gem-plugin-

which lists many available to my Debian system, not all of which I have
installed.  I think gem-plugin-magick should be enough to load PNG and
other common formats.
