问题
Say I browse to a vk community and would like to be able to retrieve all of the gifs uploaded to that community, How would I go about this?

You can use method docs.get
Access it by link
https://api.vk.com/method/docs.get.xml?owner_id=-GROUP_ID&access_token=YOUR_ACCESS_TOKEN
Read this my answer to know a bit more if you do not have an acess_token
In result you will see a document with xml-format. (if you want to use json-response-format just remove ".xml" from link you're accessing)
Document will contatin all doc-count and information about each of them like document_id, its title and size, extension and url.
Note that if you accessnig documents from community (not from user) your owner_id in the link must be negative, it must contain - before community_id
To know community id you can read another my post
Feel free to ask any questions if you didn't understand anything :)
