Using IE?
Transparency seems okay in Firefox (1.0.7).

Seems to be working now; it wasn't yesterday when I posted that.

Yes, I'm using IE.
 Emeritus Sci Advisor PF Gold P: 9,772 Somethings wrong with the AA again $$V = \int \pi \left[ f(x) \right]^2$$ I'm using firefox.
 Sci Advisor P: 1,132 I've had trouble with .png transparency in IE before. The only way i got around that was by using transparent .gifs. I know MimeTex converts to .gif, but it's not my favorite converter as it doesn't use very smooth (vector?) characters but it takes in Latex at the command line directly, rather than reading from a file which i found very useful. An alternative would be to set the background color to the background color of these forums, but since you have different styles for the PF layout that might not work. Sounds like a pain. Actually, i just found out MimeTex can be compiled with anti-aliasing on.

 Quote by chroot robphy, As I mentioned, the antialiasing done by ghostscript appears to be different now than it used to be. As I said, I prefer the old look, and am going to try to make it look a little better soon. Apparently quite a bit of stuff was changed. - Warren
What version of Ghostscript? What version and distro of linux?
From googling, these commandline options might worth playing with:

-dTextAlphaBits=4 -dGraphicsAlphaBits=4 -dNOPLATFONTS

...just a thought.

The use of $and$ I've always used in the \picture environment here
let me use the standard tags $\alpha$ for math symbols. I found this out by trial and error.

 Sci Advisor P: 1,132 Miktex has all kinds of packages available for download. In order to use these packages must i specifically indicate which to use in the latex code or is there an option to just use all available?
 Sci Advisor HW Helper P: 9,396 You won't want to use all available. It is unnecessary and there are package conflicts. You cannot use xypic with Paul Taylor's diagrams package for instance. Plus there are some packages that require their own \usepackage command and yet others must appear after other packages in the preamble as well.
