One of the main reasons I keep a cel gallery online 
is so I can look at my own cels while I'm sitting 
at the computer.  However, for this purpose I could 
just make a totally private gallery.  I have not, 
because the other reason I keep a cel gallery 
online is because _I want other people to look at 
it_.

This means that I need, to some extent, to cater to 
_their_ choice of browser/screen resolution/etc.  
Only 0.14% of my site visitors are using Netscape 
6.  More than 50% are running at 800x600 
resolution.  Heck, 12% are running Windows 95, and 
no visitor has yet come by who was running any 
Windows OS newer than 98.

Fortunately, it's really not at all difficult for a 
cel gallery to cater to a fairly low common 
denominator, while still being attractive and 
functional.  To take a recent example, the gallery 
posted by theredhood is _gorgeous_, yet works just 
fine on older browsers. (I don't hold my own 
gallery up as an example; I admit to having a total 
lack of artistic talent!)  :-)

So, if you're making your gallery just for 
yourself, I see no reason not to throw in tons of 
java, specific fonts, and "advanced" HTML.  But if 
you want your gallery to look good (and look the 
same) for all of your visitors, leave 'em out and 
keep it simple.  Getting Netscape and IE of _any_ 
version to both work the same is hard enough with 
simple code!
