aloha, jon!

why force this group of users to turn off images? why not a "suppress
flicker" or "control roll-over rate" setting? the information contained in
the roll over graphic or flickering image may be important and may be what
the person is looking for, only they need to step through the roll over or
video because they can process it more efficiently in increments then they
can when it is funning full speed or when presented with a textual
equivalent... why does user controlled freezing not resolve this
issue? for some, the combination of images and pictures may be
overwhelming, but for others it is the movement that is distracting, not
the graphic itself...
my main question is: why this urge for either or resolutions? turning
things off in the cases we've been discussing isn't an accessibility
solution -- it is a preventative measure... it doesn't provide the user
with what he or she may need to process the information in their individual
modality, only protects them from physical harm and mental strain, but does
_not_ increase the accessibility of the content... why? simply because
turning a graphical presentation off, may cause as gaping a perceptual
black hole for one user that the lack of a textual equivalent causes for
another... yes, there are requirements in WCAG and elsewhere that a
textual equivalent be presented when support for multimedia objects is
disabled, but is text always the best solution? a quick review of the CD
debate that has been raging on the GL list for the past few months would
suggest it is not the sine qua non of accessibility...
