Water, Lava, and Magma Textures

Hi!
I’ve been trying to upload a new texture for water, lava, and magma blocks which are all moving blocks. I’ve uploaded each frame into the really long canvas it offers. The magma block does show correctly on my pack, but when I use the pack, all these textures (water, lava, and the magma cube) show up as the purple and black missing texture. My textures are a higher resolution (some are 128 px wide). How do I fix this?
