# Threadjack!
but are there any good ideas how to keep background image transparency without having massive PNG filesize? Gif doesn't seem to work, and I don't want to drop a massive filesize on /board and get lynched. I can get no lower than 743k where gif would be 40k but the background borks. :(

# Upload it somewhere and we can take a look?

# Cheers.
Rather spoils the intended effect popping it on here but I'll never learn otherwise. This is the .gif

# You didn't save it as an animation, or something, did you?

# Nope!
Peter Davidson got his elephant comp gif to about 15k! Grrr..

# whack the png file somewhere and I'll see if I can squish it under 100k for you

# GIF 128 No Dither
As transparency (removed the pure white) gets it to 21K.

# ooh,
I just uploaded the PNG too!
Thanks! :) Now to test it! I won't start a new thread I think.
EDIT: Thanks all, still leaving white lines inbetween the colour changes and around the 'hidden' objects. I'll keep playing though. :)

# I dunno what stopped you gettign a transparent background in the gif.
In GIMP, I get caught out all the time by forgetting to add an alpha channel.

# a few options:
pngcrush is a somewhat fiddly to use command-line only png compressor that makes crazy small lossless files

if you use photoshop - the SuperPNG plugin makes reasonably small png files.

some other image editors/converters have compression features.

Generally though, png files are not all that small. So the next option is to reduce the resolution of the image.

# Hmm
Been looking at PNGcrush, and looks fiddly. I use Fireworks not photoshop (with a side of illustrator) as that's what I know, normally I .gif my images fine but want to play with things appearing/disappearing on the board.

# Ohhhhh, I see.
In which case I'm not being a whole lot of help. Sorry about that.

# IrfanView has a plugin for compressing PNGs
However it's not amazing. I saved your GIF as PNG with transparent background and it somes out as about 50k using the default settings, 18k with the PNGOUT plugin. I had a white background in IrfanView when I saved it.

# If the semitransparent stuff is mainly in one area you could slice it in to multiple files.
Or go for a 8bit png / gif with a matte of a light grey midway between the board's post colours.

edit: If you like the sound of PNGcrush, there's also psydk.org/PngOptimizer.php . It's stand-alone (you don't need to install it).
