:o

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. :evil:

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. :P

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. :D

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
