ZRC20 vs BRC20 Explained
One important distinction:
ZRC20 uses JSON data that can fit within Zcash's on-chain data constraints, meaning the token inscription data itself can be stored on-chain.
Images are different. A typical JPEG/PNG can be much larger than the available per-transaction memo capacity, so simply putting a URL to an image does not mean the image itself is on-chain.
