You've seen Durandal's mathematical equations, now feast your eyes on the powaaaaar of png24 transparency:

Outer glow example

Gradiant example

Drop shadow example

Drop-shadowed version of my avatar, featuring the lovely Akiha Tohno

If you use IE, you're out of luck

How many colors did it have before you saved it? Did it have transparency before?

1) No more than 150.

2) I made it with a transparent BG, but hadn't saved it yet.

Try using the optimizer to save the image. Sometimes it helps. -shrugs-

I've had it also go bat shit wrong for me, though.

I used PS7's 'save for web' feature on my av

Thing is, my av was a 1.3ish kb gif before I drop shadowed and png'ed it

I'm using the Save as web feature. I'm not so stupid as to do a normal save as.

Try importing it into Image Ready first. Image Ready has a more complete set of tools for image compression.

Image Ready... is that available (legally) for nothing?

Or use gimp. It has 9 levels of png compression (and uncompressed).

Bah, even gimp won't compress enough occasionally. Use pngcrush with the options '-m 113 -cc -l 9' which gives about 20% size reduction in addition to gimp's compression.

My 24-bit PNG sig image at another forum...

It doesn't appear quite right on the dark-blue/black theme version of this forum, as it was designed with a light background in mind.

But like Hamel said, if you use IE, you're out of luck.

There's a thing (in export i think) where it exports to imageready, within photoshop.

PNG24 is a 24-bit image, so you might have to do some trickery with the pallette first. Unfortunately, my mighty B-36 avatar suffers the same fate as other nicely anti-aliased images -- too big. I must then suffer with puny 1-bit alpha courtesy of PNG8
