image browser, a good alternative to
xv (for it loads faster),
display (for it is not a UI terror),
gqview and
ee (for it does not take over your machine nor aspires to pretty design).
It is meant to be called from a shell, as in
xloadimage mega_hard_porn/les*jpg
By hitting the spacebar you signal the program that you want to flip to the next picture. This makes xloadimage uniquely suiteable for one handed activites.
On cool systems, xloadimage is aliased to xli.
