I have run across several galleries that I
couldn't read the text on unless I highlighted it.
It was very annoying.
After I got low presentation marks and saw some of
the offenders above, I did go back and play with
my gallery colors til I found something I liked
that seemed easier to read.
I also changed graphics, again mainly from
visiting other galleries to see what annoyed me.
(That usually was unnecessary large images over
200k - since when visiting family I use dialup and
I hated waiting for big banner pics or large cel
scans to load on sub cel pages).
Another thing that annoyed - couple galleries
didn't thumbnail. Its a one click thing that
makes browsing a gallery so much easier. It got
really old in one gallery where everything was a
text link instead of a picture.
Those are the type of things I would rate low for.
