This approach will force us to do decodes and encodes. I agree we need this behavior as a fallback but I'm wondering:

If the method we call returns an image.Image that happens to be a LazyImage can we save ourselves some decodes and encodes?

Let me think through this:

For GetImageFromGetImages, we call GetImages that returns us the image.Image, which could be a lazy image. If it is indeed a lazy image and the requested mime type matches the response mime type, we hit this path when we call EncodeImage and save ourselves an encode ✅

For GetImagesFromGetImage, we call GetImage which returns bytes, we have to decode to an image.Image so no lazy benefits here ❌

Should we also add test cases for mimetypes with lazy suffix?
