Added some examples to the doc https://github.com/hzrd149/nips/blob/image-collections/169.md

Ideally the events would just be a new kind of NIP-51 lists / sets with NIP-92 "imeta" tags. that should give plenty of flexibility to add thumbnails, alt, and summaries to images so the are easier to search for

I also changed kinds to 10169 and 30169 since the original was conflicting with some stuff
