A common concern with website owners and even social media profiles is how to protect their images. This is especially big with artists, photographers, and the like. The concern is valid for those who sell images for a living and would not like to have their work ripped off. The bad news is that nothing will fully protect your images, but some smart measures can be made to both show off your pictures and keep them as safe as possible.
In this two part article we will look at four ways to help protect your images online. Stay tuned.
The first thing to do is scale those images down. You want to reduce both the height and width dimensions then also the dpi of the image. This is a good plan for load time and proper display on your website anyway, but when an image is only 640x480 pixels at 72 dpi it is not going to be able to be printed or enlarged at any quality.
This does not prevent someone from downloading your images but makes it impossible for them to do anything useful with that image. For an image at 640x480 at 300dpi the best size for quality printing is 2x1.5". When we lower the dpi down to 72 it makes that print quality even worse. Most computer displays are 72dpi so you do not see any loss in quality on the website.
Adding a watermark to your image is another good idea. A watermark is a partially transparent layer over the image that includes your name, logo, or copyright information. These can be small along one side or large across the whole image. A watermark is almost impossible to remove so the effort to steal your image far out weighs the savings of ripping you off. Couple this with a scaled down version and you have twice the protection.
