Problem trying to upload product photo

[ReynerHL]

The main problem is that it is trying to create a new folder with "products" as identifier, but the folder "product" (without ending s) already exist.
Diging into the config file, in the vich_uploader section, we note a little typo and changing "products" by "product" solved the problem.
Hope this helps. And congratulation for the great example.
