the automeme feature is what I mean

Some older automemes are included in the tag here, look for the "Created with the Imgflip Automeme Generator"

imgflip.com/tag/automeme

So this feature is as old as imgflip almost?

Old, but not quite as old as Imgflip almost.

Oldest images on Imgflip are from June 2011, automeme showed up sometime in summer of 2018 I think.

Oh okay.
