I don’t know the exact specifics as I left it largely to him to solve, but it came down to taking the function for selecting a random header image from another theme using the same framework as Hiero and putting that code into functions.php and header.php in the Hiero theme.

I can perhaps ask him to come by and give a better response, but that’s as well of it that I know.

I’ve since gotten my problem solved by a webdev-savvy friend who ended up taking the random header image functionality from another theme using the same framework and hacking it into the Hiero theme.

I could try and write something up for future searchers, but I can’t guarantee my series of events will get the correct/intended results.
