Hi,

I love pixelpost the way it is, except for one thing: I´d like to use the .png format for thumbnails instead of .jpg due to images with transparent soft edges. How do I do that?

internet explorer and other older browsers wont see/rended the alpha channels

my suggestion is to no attempt this until the next IE version takes up a majority of IE users

blame MS, they're WAY behind

png for more sharp edges? ummmm does it help? I assumed, the down sampling will kill the edges.

no... for transparent edges - as jpgs don't have a transparent capability. not sure how transparency is needed for photos though.

Thanks for your replies.

You are absolutely right of course but I gotta say I really don´t care about it. I´ve managed to get my photoblog to look right in all recent versions of the most popular browsers and that´s enough for me.

So can it be done, can the thumbnails be changed to .png?

Yes, they can but you must creat code for PNG on your own hand :)

:) yeah, that´s what I´m going to do. I wasn´t asking the people here to do it for me – all I need is some hints where to start (e.g. which php file(s), which lines?). I´d really appreciate it.
