Over the years I’ve seen many methods for “protecting” images on the internet. Like scripts designed to prevent saving of images. Loading images as the backgrounds of tables. Obstificating the source in webpages.
Unfortunately the nature of the internet means that the only way to “protect” images from being downloaded is to not put images on the internet.
Well wouldn’t the internet be a boring place without images, what would happen to all the lol cats?
Once you have gotten over the fact that the internet downloads copies of your images to every computer that visits your web page. Then you can consider ways of “protecting” these copies.
The obvious way is to put watermark/logo/copyright/credit on the face of the image. That’s a valid tactic but you have to balance how much the image is covered with the watermark vs how much you want your image unadulterated.
Another just as valid tactic is use lower resolution or smaller images.
That’s the tactic I generally use. I keep the full sized images for myself. The images I let out into the wild are generally only 1/4 sized or smaller.
The size and resolution are adequate for online viewing but leave something to be desired for enlargements.
When I work with a model I give them copies of all the usable images. These images are also 1/4 sized with minimal post production. That way they can retouch however they want.
I sometimes also include my “Damagedi” logo in the bottom left of the image. Depending on the background of the image where it’s placed its sometimes mistaken for an artifact left over on the image. ;0)
