Images of dental services cannot have white-spaces

[MrDave1999]

On Windows there are no problems but on Linux distributions when a file name has whitespace, it is appended around single quotes. This leads to invalid behavior, because in the database the image name is stored without single quotes but in the file system it is (this should not be the case).

This would cause problems, for example, when you want to edit the image of a dental service, it will not be possible to delete the old image because the image name in the database will not match the image in the file system.

Sample:

File system:

'brackets_0023222.png'

database:

brackets_0023222.png

Apparently the app still works on Windows 10 or Ubuntu even if the image name has whitespaces. Likewise, it would be nice if could replace the whitespaces with underscores to avoid possible problems with other operating systems.
