Comment (by richbhanover):

 Thank you all for your extremely kind responses. As I said in my [note on
 the forum,](https://wordpress.org/support/topic/randomize-header-images-
 not-random/#post-13641522) I have done some modeling of my own, running a
 Python program several times, to look at the distribution of
 random.choices() from a set of 24 items. You’re correct: the distribution
 I presented doesn’t seem to be out of line for actual random selection.

 Nonetheless, my concern is one of user experience: Images don’t appear
 random to the viewer. As I noted:

 * The same images frequently appear two times in a row.
 * A few images frequently appear several times “in a cluster”. This
 doesn’t "seem" to be random (even if it is, numerically).

 I'm willing to leave this ticket closed for now, but have these follow-up
 requests:

 1) Where is the code (what source file) that performs the randomizing?
 2) Does the randomizing code have any notion of the "last image shown"? (I
 am thinking of letting the next image be "n+random(0,5) modulo number of
 images" so the next image "walks progressively through all images."

 Thank you again.
