    What's wrong with the current Photoshop implementation? I use it fairly regularly and have great results for the images it's appropriate for.

    Key words - trying to kill.

    You were claiming that implementing DRM will limit your audience. For the general public, that's simply not the case.

    DRM-laden content is very popular with the masses if it's accessible enough. Just look at services like the free version of Hulu or any streaming video using Flash.

    you do know that JPEG is only 8-bit right? convert the image to 8-bit first if you want to compare size.

    You don't know what you're talking about. JPEG is 8-bits per channel. There are 3 channels. A 24-bit PNG is also 8 bits per channel x 3.

    I do agree that JPEG is more widely accepted though. PNG is still thought of as a graphics only format, probably because of the optional alpha channel.

    It's also down to what PNG compresses efficiently. PNG uses DEFLATE so it handles solid colors very well. JPEG uses discrete cosine transforms, which essentially is a mathematical model of the image data - similar to to how MP3 compresses audio. It handles complexity much better than PNG. Just because major web sites and services crank up the compression ratios and produce lousy output does not make it the fault of the format itself.

    Have you been to a major web site recently? Lots of HUGE images. Some of the flashier sites have a full-width background photo. Most headline photos are 500px or wider.

    DRM is copy-protecton (and view protection in some cases).

    IPTC/EXIF can already embed digital signatures. There's really no need for a new standard for that.

    With all of the image modification tools out there this won't stop anything

    And to open the image, they'd have to implement DRM. Any tool that implements it would be forced to make the image read-only upon opening.

    With all of the screen capture programs out there this won't stop anything

    Already a solved problem with HDCP. Graphics drivers will not let you screen capture it.

    With all of the DVI to HDMI cables to capture cards this won't stop anything

    Any real-world implementation would involve secure content path and require HDCP.

    With all of the other formats you could re-save it as this won't stop anything

    You would still have to be able to open it in something first.

    Facebook doesn't want DRM. How are they supposed to re-compress uploaded pictures if they are DRM-protected?

    I took a random 833x1200 portrait photo from the Internet and loaded it into Photoshop to compress.

    The 24-bit PNG is 941.4 KB. There are no areas of solid color that benefit from PNG's efficiencies. Just for fun, I ran it through an online PNGCrush tool and it somehow jumped to 1.5MB.

    The JPEG at 100% quality is 311.6KB
    The JPEG at 94% quality is 260KB
    At 80% quality it goes down to 179KB
    At a web-appropriate 60% it's 133KB and still looks nearly-flawless, with only a minor loss of detail around pores.

    If I'm a professional photographer, I would probably still save to JPEG at 100% for final output instead of RAW or TIFF. And even at 100% it's 1/3 of the size of the 24-bit PNG.

    if ANI/ALI information is not present at the time the dispatcher begins typing in the CAD Incident Entry window, source data is not captured, and dispatchers would need to manually port source data into the CAD Incident Entry window

    That's a SOFTWARE issue, not a butt-dialing issue. When the information finally comes in, it can be recorded on the record asynchronously if the software is designed correctly.
