I believe there are options on the set-up, though I am not sure if you
can disclude the empty Alt tags... and maybe it should not be discluded.
My thoughts or feelings,... Some authoring tools may *automatically*
place alt="" into an image tag if a user does not specifically fill that
blank or give that description. That warning[it is not an error to
include empty alts] may flag and make the user aware of one or more they
may have meant to include but forgot?

Personally, I prefer to use the Cynthia Says model, and check against
the WCAG [all priorites], and Section 508[which I feel is weak in
several areas]. Checking and Meeting Section 508 only, may overlook some
key accessibility factors.

You are not alone, and I find the graphical interface may be very
confusing or overly busy. I imagine this tool might be overly busy or
distracting for some users. I would prefer the plain text checking mode,
though there are some added benefits to Wave [checking for linear
readability, etc...] , that are not present with other
validating/checking tools. On the other hand, the graphical interface
may be an excellent option for others.

I agree, though they are quick checks for stand out errors or problem
areas. It is a part of the package when I check documents.
