Ubuntu graphics program

[delilahjed44]

Hey everyone, I am using Hardy Heron. I loaded a graphics program for altering jpegs and that of sorts, ( NetPBM ), but its not in the application after it has been downloaded from synaptic, I did a search in the system and found these

./
usr/
usr/lib/
usr/lib/libnetpbm.so.10.0 < thought this was the exe. so re-installed it.
usr/share/
usr/share/doc/
usr/share/doc/libnetpbm10/
usr/share/doc/libnetpbm10/copyright
usr/share/doc/libnetpbm10/changelog.Debian.gz
usr/lib/libnetpbm.so.10


Still I cannot find any file pertaining to the program in order to open it. Not sure what path to use in the terminal if any?

Can someone lead me here into the right direction?

Thank you
Sherri
