Steps to Reproduce: see issue on stack: http://stackoverflow.com/questions/8050555/imagenew-tobase64-encoding-issue-with-loss-of-quality-in-coldfusion/8067729#8067729

 toBinary(image );

Yeah I get the same issue when creating an image upload function and pngs need resizing. There is loss of quality and transparent pngs look horrible i.e. colours are messed up.

the reason for this issue is that png's are being converted to jpg so any transparent png gets tunred black there is also a loss of quality during this process too. png SHOULD not be tunred to jpg

glynjackson - Re: "not ideal as all my image are now converted to png" If the image source is a physical file, just use the file apply it conditionally (ie only when it is *.png)
