I think that there is no free software based out-of-the-box solution available. But you can combine a number of useful free software packages to get the job done: Sane for image aquisition; and tools like ImageMagick, the pnmtools or similar for image format conversion. Ghostscript can produce PDF files, provided that you have Postscript data available -- and there is more than one way to write Postscript files from "pixel images". Other members of this mailing list have already mentioned them. You can "glue" these programs with shell scripts, written for bash, csh or the Korn shell. Alternatively, yxou can use a more advanced scripting languages like Perl, Python or Ruby to get the job done. Python has even its own "pixel image manipulation" package, called PIL.

Have a look at Gift (GNU Image-Finding Tool): http://www.gnu.org/software/gift/gift.html It's in a quite early development stage though. If you simply need a sort of a "photo gallery", you might look for some web applications. There are probably PHP-based solutions available; alternatively you might try Zope (http://www.zope.org) and one of its additional products for photo galleries. (But I should mention that Zope is quite complex beast...) Abel
