around each image/caption group. This permits big thumbnails on
small screens, and if the screen width doesn't permit many across the
screen, then it re-flows them to put fewer on each row.
All users' displays (for practical values of "all") are between 1000
and 2000 px wide. The few smaller than this can cope with some
sideways scrolling and a competent fluid design. Anything bigger than
this is either wall-mounted rather than a desktop, or is on multiple
screens. Either of these require different thinking from the single-
screen at arms' length model.
Phones are easy. Their networks will transcode images on the fly.
The remaining awkward clients are palmtops (my Nokia 770) etc. These
are around 600x200 in size and don't generally connect through a
transcoding network proxy. OTOH, I don't _expect_ this sort of ultra-
portable device to be convenient to use for huge images. However one
of my main uses for it is viewing >1000px-wide images (references on
silver hallmarks or signatures, from within auction and sale rooms),
so don't rule this out completely! Sometimes awkward scrolling is the
right behaviour, better than preventing access altogether.
A very good approach (requiring significant effort though) is that
used by wikipedia, wikicommons and mediawiki for handling images.
They're uploaded in any size up to "vast" (look at the Torre del
Acqua, Barcelona photo on Wikicommons) and the site publishing engine
re-sizes them as necessary. The size served depends on the context, so
a "thumb" or a "gallery" image on an article page is automatically
smaller than the image's own page. The size for each of these contexts
is also defaulted to a user-specific setting, which is adjustable for
large or small preferences.

Most mod browsers can be set to adjust displayed image size to fit the
viewport. Thumbnails should be big enough to see at higher resolutions and
small enough in filesize to download quickly. There is no hard-and-fast
"rule" per se, but if you lack common sense you will commonly have trouble.
