Any suggestions on bringing the file size down? I've tried interlacing the .gif the current size is the lowest without image degradation.

Just for comparison, I took the image into PaintShopPro (yes, I'm too cheap to own Photoshop right now)

and thats good, because Photoshop has worst savers for JPEG and PNG I've ever seen! (even if you use Save for Web).


Use JpegOptim. I've done quick'n'dirty Win32 port: http://pornel.ldreams.net/jpegoptim/jpegoptim1.2.2_win32.zip

and for PNG absolute must is:
pngcrush.exe -cc -reduce -rem gAMA -rem cHRM -rem iCCP -rem sRGB -d pngcrushed file.png
optipng.exe -o6 pngcrushed/file.png


pngcrush will remove gamma chunks from png, that may cause unpredictable results on different operating systems and optipng will squeeze few more bytes from png.

Photoshop doesn't support 8bit png with alpha channel at all, but they are very very useful.
PNGQuant converts 24+8 png to 8+8. Great news is that IE partially supports those - instead of making gray background it just degrades alpha channel to 1bit.


all mentioned programs are open-source. link: google.
