- Create a better (more) re-usable flow for downloading images to disk and inserting images into the db
- Validate images properly by reading them fully and using DecodeConfig
- Fix some security issues by re-encoding images
- Always outputs one format `jpeg`, which keeps everything "normalized" and adds compression to images (mainly user uploads which might be big).
Now that we have everything encapsulated in Services, we can move the db parameters of each function into the service struct itself which:
1. Simplified calling and reduces us passing around the db in random funcs that just pass it to a service func
2. probably other stuff
3. looks nicer now
