    hi there -

    I have a few png files with transparencys in them on my website - the file size is nearly half a meg on some of the larger images.

    I need to compress them as the load time is annoying me.

    I've tried changing the format to jpg, gif etc... but the transparency's dont translate and show up as white.

    So does anyone have a way to do this on a mac. MS has a program to do it called crush png?

    Let me know what you guys think?! for reference.

    There are also some PNG optimization tools that are better then what's available in CS3/4, however don't bet them to reduce a half a meg file to something reasonable. You may need to go on a slicing spree or reconsidering having a PNG. Transparency adds a lot of extra data.

    converting them to a gif with Alpha ticked in preview did the job fine! -

    Thanks... 400 kb to 24 kb - not bad eh?
