Thanks for the sites, I didn't want to have to manually edit the individual pixels, and this seems to make it so much easier.Ok...
Go to this site and turn the image into into a png, meaning it has a transparent background. Save that.
Image search for 3 cool pics that go with each era, then go to this site and stitch them together horizontally. Save that image.
Then go to this site and choose the stitched pic as the first/ background image and choose the png of the words/symbols as your second/ foreground image.
You can adjust the size and placement and a few other little tweaks to get it just right. Process it and, boom, you just made a custom overlay meme.
I could have done it in less time than it took me to write this. Post results, I’ll start making my own attempt right after I publish this reply.
Protip: Make sure the words are clearly visible against the background or maybe switch the font color/s to be instantly legible to the scrolling eye.
Clean and simple, nice.
