The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Here's a few animations on a 24x24 matrix with an accompanying github repo in description
Two ways 1. Decode gifs in mcu(requires good mcu) https://github.com/pixelmatix/AnimatedGIFs 2. Encode gif to good for mcu format https://github.com/sutaburosu/scintillating_heatshrink

Image array into ESP32
It's right there in the root folder of that repo. It's no use by itself though; it converts to a custom format that only the included sketch can play back.

Is it possible to switch to another pre-built palette using pointers?
Perhaps this would suffice?

Most modern A/V codecs won't fit in that limit by several orders of magnitude.
Even standard-compliant JPEG decoder would be hard to squeeze without some serious codegolfing. Discarding some barely used features gets you close to that limit, though [1].
Smallest popular TCP/IP stack [2] is ~20kLoC.

Your imagetwo[] is a JPEG file. You are displaying the raw JPEG data on the LEDs. It needs to be decoded first. Maybe you could use picojpeg to decode it.
