A deleted picture does not take up space. The area on the hard disk is
no less available than if the file had never had been written. It's that
some of the 0's have been changed to 1's, and that does not make the
disk spin any slower.

Writing files and then deleting them can contribute to fragmentation of
the available space, slowing response when it gets bad, though.

The main point is that the lack of deletion is of concern only where
security is important, but not at all to ordinary users.
