Ubuntu Multimedia :: Create A Set Of Contact Sheets Of A Directory Of Digital Photo Files?

The only thread on creating a contact sheet appears to be years old & locked:- (photography) how to create a single jpg /tif contact sheet? So may I ask what's the most common method today of creating a set of contact sheets of a directory of, say, 500 photos (on Ubuntu 10.04 lucid)? The only thing I really want to specify is the grid (e.g., 4 photos by 6 photos, or something like that).

imagemagick
gThumb

For example:

Code:

montage -label "%f" -frame 5 -pointsize 10 -geometry +4+6 *.jpg index1.jpg

This supposedly creates an 4x6 grid of images with a label under each image (of pointsize 10).Here's another example from the net:

- ImageMagick Thumbnails and Contact Sheets

What do YOU use to create a decent contact sheet set out of a large directory of photos?
