strange, tried png8 myself, but all images looked kinde gif-like
edit: ok, now i remember - png8 sucks here. white borders, no transparency.
if the file size is a problem, i would prefer classic jpg with rounded borders -> better quality + smaller file size
Did you use Photoshop? Because some other software may produce really crappy looking PNG-8's.
If we only wanted speed, JPG would definitely be the way to go as it's 5 times smaller than PNG-24, without any noticeable differences. However the problem is rounded corners. JPG cannot do that, which is why it sucks.
The way I see it, we have a choice between:
1. PNG-24 with perfect quality (60k)
2. PNG-8 with good quality (18k)
3. JPG with good quality but crappy corners (12k)
I like option 2 the most.
