Hello to all,
see there are lot of exe in IM installation.

See also expert use of these instruments to accomplish different task.

Now i have some question:
- how identify if a files is really an image (my users put email, pdf in my INPUT directories)
- how identify image type from header (if is possible)
- how maintain image dimension (W x H) but reduce Kb size.
- how strip all IPTC info (or other info) contain by image file.

Sorry for boring question, but i think can be usefull also for other forum user

Thank you,

m.
