Repository of animal / scientific images with scale bar for reference, starting with a common leopard frog Lithobates pipiens.

I don't want to keep bugging you or depleting my AI tokens for the day - I want to find an archive of images that illustrate a variety of animals, but one illustration of each animal must have a scale bar with a measurement showing the exact scale of the image taken.

Copilot suggested:

Animal Photo Reference Repository

PhyloPic

MorphoSource

And none of them had an image of a leopard frog with a scale bar next to it, so I'm guessing they're all useless.
