Best way to fetch cover art for multiple release-groups?

Hi,
I need to retrieve cover art for multiple release-groups when I already have their MBIDs. Is there a recommended way to do this efficiently without hitting rate limits, or do I need to request each one individually from the Cover Art Archive?

Thanks!

Check for availability of release-group cover art

You have to request each one individually. The images are hosted by the Internet Archive, and I’m not aware of any specific, documented rate limits they have for downloads, though they do have occasional issues with service availability.
