Hi,



Can someone please let me know what in their opinion is the best .png/.ico icon editor/creator for Vista x86 and why?

My reason for asking is, amongst other things, I want to increase the size of a 'Thunderbird Email' icon I have in the dock. Please refer to images.

I have a 256 x 256 and 512 x 512 .png version of the bird, but I want it's height and width larger if that's possible.

Thanks in advance for your help.

Warmest Regards, Neil
