[BUG] config: remove numbered image naming option

Currently we're counting the files inside the images folder or reading
database lenght to get the image name.
We are not really checking for the next available number which could
cause that we're loosing made images.

- Example 1:
  We have 3 images: 0001.jpg, 0002.jpg and 0003.jpg
  Next image-name will be named 0004.jpg
  *Everything is fine here*

- Example 2:
  We have 2 images: 0001.jpg and 0003.jpg
  Next image-name will be named 0003.jpg!
  *This will override the already existing 0003.jpg!*

Since i have no quick solution, let's disable numbered image naming for now.
