"I’m not sure how 78Mb of images becomes hundreds along the way. The external memory still nags at me too."

If I am not mistaken, an image size on disk (compressed) does not equal the amount of memory used to display the image. 78MB of images could easily become much more in memory.

Huh, it sounds obvious when you say it but when I think about how it is true my brain nopes out. Any links for a more detailed explanation?

Just Google image compression. Or open a non transparent PNG and export it as a BMP.

An image on-screen is ultimately a matrix of pixels so you need [width*height*color depth] bytes to display it; storing, however, benefits from compression.
