Chip-
Yes, it's the black-on-grey that I have trouble with; and with any
combination in fact, that doesn't offer the best contrast, e.g.
black-on-white. Old eyes, you know...
Also, I note, under Firefox/Win XP with the NoScript add-on/plug-in in
effect, that Firefox prevents pupman.com from automatically reloading.
Normally I just click on the Allow button associated with that and it
reloads. And why it should need to reload, I don't know--but Firefox
won't let it for whatever reason.
As to a banner, one often sees a strip of images with arrows at each end
for "sliding" them along. Could be a way to do it.
Will you have a risk in accepting images/videos for posting that might
incorporate malware? If so, maybe just requiring upload to a site such
as Dropbox, that you would establish just for the purpose, might solve
that. Would eliminate the possibility of a hack into your Website--at
least, via that method.
