Sizing Photos To Prevent Copying

    What's a safe size to post a photo at that will protect it from being made into prints? I'm posting photos of some of our gallery images and need to make them low enough quality that the artists can rest easy about their work being online. An example of what the size is now would be 3831 x 3326, and I know it needs to be a whole lot less, but still want it sized big enough to look decent. Thanks for any help.

    72 pixels per inch (PPI) is fine for the Internet and makes lousy prints. The other option is to watermark them. I'm sure there are more sophisticated ways to protect images, and nothing is without someone trying to figure out a way around your security.

    Your question mentioning numbers is only relevant when you also include the size of the image. At a smaller size, 8" X 10" or thereabouts, that would be ample to print, at 40 X 60, not so much. The total pixel count needs to be related to the image size. An 8" X 10" image at 72 PPI is 576 X 720.

    I remember Mike having issues with someone lifting images from Andy's web site. He imbedded a photo that he said wasn't too pleasant, so that when someone tried to copy their images, they would get this particular image.

    There's been a rash of image stealing on the Internet. There's not a lot of recourse other than to expose the offending party and publicly shame them into taking down the stolen images.

    Thanks, Wally. Last year, I shared a gallery image and some innocent family friend wrote that they loved it and were going to print it off. I let them know that wasn't appropriate. It brought to mind the time a friend said she was glad I'd bought a tape and wanted me to copy it for her. She said so while standing in front of the pianist whose tape I had just bought. I said, 'I won't copy it, but I'll buy you one', and did so.

    A quick and easy way of resizing pics is to use Microsoft's Picture Manager - edit pictures- compress for web pages. This will bring a 67kb image down to 18kb which is o.k. to view but useless for printing to any worthwhile size.

    It is strange how people who would never dream of stealing a physical object from someone have no qualms about stealing intellectual property. It started long ago with photocopying from text books but the internet has now taken it to a whole new level.

    If you are a bit more tech-savvy than me here are also clever ways of disabling the "right-click - save as...." way of downloading pictures on a website.

    Yes, you can disable Right Click but just about anyone who wants your pictures will be able to download it. Easy to get around. It will only dissuade the less technically savvy. Not worth the effort. Watermark any pictures you don't want stolen.

    I'm not an expert, but from what I've read looking into this for myself, this is what I've found.

    The ppi (pixels per inch or dpi dots per inch, generally interchangeable) doesn't really matter. It's the total pixels in the image that matter. If you put up a 3000 pixel image, it will display at 72ppi on a computer monitor no matter what the original ppi was. (although I don't know if there is a standard ppi for monitors anymore. I think there was at one time.)

    It doesn't really matter if you uploaded your image that was originally 72ppi or 300ppi. If someone right clicks and saves, they now have a 3000 pixel image. They can print it at whatever dpi they want. Printed at 300dpi, they will get a 10 inch print.

    When putting up images on facebook, I've usually put them at 1000 pixels max. Although I'm thinking I might do 800 pixel max as I'm starting to redo my website (which I haven't touched in over a year and some of those images are at high pixels.) 800 pixels should look plenty good on a monitor for a customer to see if they like an image and low enough if someone grabs it, if they print it big, it will be pixelated.

    Now, this is not to say that a person can't take a small pixel image and make it bigger. There is resizing software out there. I have a good one for working on my own art photos if I want to print something large.

    I also usually (not always, but I should) put a watermark on my images. Not in the corner, that can easily be photoshopped out. Something right across the image. But nothing obtrusive, just barely there so it doesn't hurt a potential customer looking at it, but would be a bother for someone to try to remove it if they did want to try to print it.

    Nothing is sure fire, but you can make it a little harder. Just like if someone really wants to break into your house, they can, but you don't make it easy for them.

    Hope that helps.
