jpg vs png

[Thomas Chung]

Does anybody know if there is any patent issue with jpg?
I know gif has patent issue that's why we should use png format.

"PNG format is a patent-free compressed format. We hope it will become
widely supported; then we will use it. We do have PNG versions of the
images on this server. "
