Limiting memory usage?

[starseeker]

Hi! Very interesting program - came across it after discovering Galapix, was hoping it might be a solution to exploring a collection of very large images across multiple directories - I've been looking for a nice solution to that problem for a while now.

Over the years I've saved a lot of images like the following from the National Archives site: https://catalog.archives.gov/id/18558251 When I start pix-image-viewer scanning the directories holding them, it seems to quickly max out available memory.

Is there a way to cap how much memory it's using when things are "zoomed out" and lazily load when zooming gets more aggressive?
