Hey its Linux, and a workstation,  no reboots :-)  To track memory usage 
open an xterm, use top or htop. I can watch the memory usage 
dynamically as I browse thru images with Gwenview, and starting, 
stoping other apps and vm's.

I tried browsing a folder of jpegs , I get the same results as you did.

This is something the tiff files do not do, memory usage increases until 
it is all gone..fairly quickly on some tiffs. The tiff 
format  "structure was designed to be easily extendible", and can vary, 
though the files I get are from a service that scans drawings and 
supplies tiffs to members, should be typical.
