This question already has an answer here:
I have ~ 900 pictures (mostly photos) of varying sizes.
Now I want to create one big picture that includes all 900 pictures in a small thumbnail-like resolution. The tool should automatically resize the thumnails so that everything fits. All pictures should be added next to each other, so there should be no border/padding.
Each picture should be included exactly one time! (however, it would be okay to omit a few so that there is no empty space)
I'm looking for a tool (FLOSS, for GNU/Linux) that can do the job.
I tried Metapixel, but
- it needs an input image that should be "resembled" by the thumbnails, and
- it only uses a selection of all pictures.
I found montage, but couldn't get a result yet, because my system was unresponsible for hours after starting it. Maybe there are some tweaks?
