lossless compression of still images - recommendations?

I'm making a long series of exposures of a landscape where there will be
only very small (but potentially significant) changes from frame to
frame. Basically I'll take a 5MP image every 5 seconds for a year, I'll
want to timestamp the images and keep them all for later
post-processing, as well as being able to retrieve the image closest in
time to a specified time and date of interest (which I can't predict.)

I want the retrieved image to be faithful to the original, so I'd like
to minimize storage needs by compressing the mostly unchanging parts
(the landscape won't be moving much.)

Does anyone have a recommendation for a program to do this?


In modern fantasy (literary or governmental), killing people is the
usual solution to the so-called war between good and evil. My books are
not conceived in terms of such a war, and offer no simple answers to
simplistic questions.
