[BUG]: Numbered images logic needs an update to prevent overriding existing images

[andi34]

Describe the bug
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!
