[FM Discuss] PNG Transparency lost on image resize

[Alchemy]

Hi,

Today I uploaded a small PNG with alpha, and it worked fine.
Then uploaded a slightly bigger one, and it seems after it gets  
resized the alpha channel becomes black.
Here is an example of what happens:

OS X 10.5 now gives all screen captured windows an Alpha Channel with  
drop shadow, here is the original:

I was gonna lodge this in Trac, but it seems to be down?
