I recommend Photofiltre. It's a nice piece of French freeware and does a brilliant job of size reduction and many other things too. Lots of filters and stuff. A very large size reduction inevitably reduces the resolution, but Photofilre does it very well indeed.

Why don't you post a link to the larger image(s) and let people here take a crack at it? I mean, 64x52 is small enough to be pasted in messages as a reply here.


Great idea! Upload the parent image to some host or other and post the link here. Let's see how all the contenders manage the task. Chocky bickies for the winner!

@XDelusion

Here's what I got using Photofiltre (freeware) on your large image. The resolution of this (right) and the Photoshop one (left) are the same. Displayed together like this, I don't think there's a great difference, but there is some.

Maybe the right one has a more defined outline and looks very slightly 'slimmer'. This is a difference in antialiasing.
Looking at these magnified in a different viewer, the Photoshop one has less contrast and looks more washed out.
I think the original image needs to be improved to get anything better. It looks like a cut and paste has been done, so there's no antialiasing around the outer edge. This causes Photoshop, etc to do a lot of work on the outline. You may be losing some pixels there. The only way to improve the apparent detail on images this small is to add it manually pixel by pixel.
