Like many of you (I'm sure!) I've been "pin"spired by quite a few things I've seen on Pinterest! Most of the time if there is a lesson of mine that is an original, I'll put a "pin it" button on the bottom of the post, but now, I'm pretty much granting full pinning rights from my blog to Pinterest because I have this handy dandy "permission" pin over there>>>. You can get it, too, if you like your stuff pinned!
One thing that I have done more of lately, however, is watermark my photos that I use in blog posts. I'll never forget the first time I saw one of my students' projects on Pinterest and it had been snatched with no credit given to me (or to my student, I should say!) and had been repinned 57,000 times. Yes, 57,000 times and someone passed my exact photo off as their own....so I've been watermarking more. It's a good idea that you do it, too.
While in Art we're all "borrowing" ideas from one another, from a Master, a children's book, something in nature, or an idea on Pinterest....our artwork belongs to our kids. Make sure you've given yourself credit!
There are a lot of photo editing programs out there that will "batch" watermark your photos for you. For ease at school I prefer to use Picasa, and at home I like Lightroom. If you need help watermarking your photos in either of these programs, leave me a comment with your email and I can email you instructions!
