Description/Steps to reproduce

1. https://github.com/ChickenKyiv/recipe-api-only/blob/master/docs/FreeMenu.md
   as you can see - images are broken and i think i delete them from main repository.
   in previous releases i think you'll find them: https://github.com/ChickenKyiv/recipe-api-only/releases
   But please move that images to this repo: https://github.com/ChickenKyiv/creative
   I'm trying to make code as clean as i can.

2. here you also can figure out that i upload logos of ChickenKyiv(CK) project.
   https://github.com/ChickenKyiv/recipe-api-only/tree/master/client/assets/logo
   https://github.com/ChickenKyiv/recipe-api-only/tree/master/docs/logo

But some of files are duplicated and also moved to https://github.com/ChickenKyiv/creative/tree/master/logo

You need to compare that files and move non-duplicates into creative repo and delete them from recipe-api repo

3. at creative repo we have a file, related to our current DB schema. But we also have it in recipe-api.
   Please remove it from rapi and replace path at readme file - so image will be picked from creative repo.

Expected result
