feat: reintroducing thumbnails (#3821)

* Reintroducing thumbnails

* Aligned with linting rules

* making recomended code review change
- changed method names to start with lower case as they are not used outside of their package
- made receiver types for struct funcs to be pointers to not need to create copies

Trying to cover all linting issues
- converted slog warning to use attributes when logging warnings
- seperated imports to have package files in their own section

* Update go.mod
