I think Kevin Hoyt had some code that extracted the thumbnail thanks but we use coldfusion server side to build a pyramid of thumbnails that we store for later use. from EXIF data, check this stuff: if the EXIF bits hold the thumbnails, then i guess our PNG round trips should be doing away w/those. which confuses me even more. http://blog.kevinhoyt.org/2007/12/18/samples-updated-for-air-beta-3/ thanks.

Have you opened the images in your browser? They may be in CMYK, or in 16 bits per channel.

RE: [flexcoders] flex not displaying JPEG images
Can you repro yourself? Use some tool to generate a 150DPI image and see if Flex can show it. Then add thumbnails, etc until it dies?

You could try reading the raw bytes of the JPEG and actually extracting the thumbnail if it's embedded (depending on what you're doing that could actually be a huge performance boost if all you need is the thumb).
