Re: [RCD] Re: Corrupt mail.gif - using PNG

[Chris Fordham]

png transparency only fails in IE6 and below, not IE7
you can do larger than 256 colour gifs, but they are not lossless
size is not really comparable because it depends on how many colours are  
being used - png uses selectable palette

so my advice is use what is required...
i generally use png for images that don't have a large palette (this is  
where jpg is appropriate)
i use gifs where i need transparency, otherwise png or jpg as above

the best way to see whats best for non-transparent images is create .gif  
and .png and see what is smaller..

Well, it depends. It's not as easy as "GIF is bad, PNG is good".

GIF:
        -) 256 colors only
        -) small in size
        -) transparency works

PNG:
        -) true color
        -) larger compared to GIF
        -) great transparency support, but broken in IE

Both have lossless compression (not like JPEG).

So it depends on what you want to do with your graphic and if you need  
true color or not. If you don't use transparency it's fine to use PNG  
within IE, if you don't need true color use GIF because the files are  
smaller.
