Extend image attributes to disable pinterest "pinning" by utilizing nopin="nopin" within html img tag.
No. Once this plugin is activated, you will have to add nopin="nopin" within the images that you wish to not have pinned.
Yes, it's possible. If you use any other attributes other than the ones listed here, they will be removed by activating this plugin. If you only use any of these attributes, then nothing will change.
If you find I've missed a common attribute, please let me know through the support tab and I will add it to the list.
