I personally have always avoided the use of folders, maybe
because most of my projects were large merged projects, which
already contain multiple project "folders." Also, renaming/deleting
these beasties later on can be a bear, as evidenced by many
angst-ridden threads in this forum.
Let RH place them in its own "virtual" Images folder and
leave it at that. Unless...do you feel lucky?
By the way, best practice (at least mine) is to name
everything (projects, topics, graphics) with no spaces, very brief,
and possibly with 2- to 3-character prefixes to more easily
identify them (possibly application features, for example). Such
as: sa_user_cfg.gif for a screenshot of the User Configuration
window for System Administration.
Good luck,
Leon
