Sometimes they only want the image to draw readers, because the image is a good one, or related to the writing. I don’t have a problem with that if the writer asks permission or at least links the image back to me. I’ve had a few people contact me to ask to use my hydrangea photos. And I’ve had others simply take the images – usually with links back, but sometimes not.
WordPress offers a “reblog” option where someone can re-blog the entire post from one blog to their own. It can be turned off by the blogger. I have re-blogged from others, but I always ask permission first. Even without permission, it’s a good thing to have your blogpost show elsewhere to further readership, IMO.
The use of images is what bothers me. I’m a designer for an online print-on-demand site and I’ve had my design images stolen and then put up for sale at Amazon by downright dirty rotten thieves. They know what they are doing and they steal from lots of people to make a quick buck. The owner of the artwork must then spend lots of time filing notices to get their stolen property removed. And that doesn’t always work either. I’m betting that I will still find lots of my images for sale on Amazon. I get tired of looking.
Some internet users are simply ignorant of the ways of using images. Pinterest tends to have beautiful images with no links, but that is not the only place.
Bottom line is photos, illustrations, pictures in whatever form, came from someone. Give credit where credit is due. When you see something you like online, make sure it is free to use for yourself. Contact the owner if possible, or better yet find free to use images at sites like Pixabay, where all images are safe to download and share.
