The F6 key is used to set configuration. Currently, this only sets the
default picture sizes. If you specify zero, then it will use the user
configuration, otherwise it is saved with the puzzle set, and will be
used when adding new pictures. You can specify multiple sizes; it will
create it with variants of all of those sizes. You can also specify the
same numbers multiple times if you want multiple variants of that size.

The F7 key copies a picture.

The F12 key allows entering a SQL statement. If there are any result rows,
only the first row and first column are displayed.
