I use imagemagick for that

cd myphotodir

montage -geometry 1024x768+0+1 -tile 4x3 -background Dim\ Gray *.JPG myresume.jpg

Take care of not having a file named 'myresume.jpg' in that dir or it will be overwritten. Modify the parameters to suit your needs.

To remove duplicates or n-plicates in the current directory tree use rdfind

rdfind -deleteduplicates true .

All photos are renamed with perl to include the timestamp in the filename. Thus If I want to see for example all photos of 27 sept in any year, a simple bash command connecting find with eog will do the job. I can pass then the list of photos to imagemagick. Very useful to see grow changes in the garden or in children birthdays for example.

And then perl is connected with postgresql
