Document how media files are shared in GBIF

[CecSve]

Document how media is shared in a resource and how the images are rendered on GBIF.org. Consider including the follow categories:

• hosting of media
• how the caching of images work
• resolution quality
• size limitations(?)
• formats supported

Is this blogpost relevant to the chapter? https://data-blog.gbif.org/post/gbif-multimedia/

[CecSve]

Yes, very much. Thank you!

also document what the link below an image in an occurrence record is populated. Currently, we have one identifier field in the occurrence media table, but multiple sources can be published by the publisher if they use extensions, so it is unclear what happens behind the scenes for populating the field.
