24	+ The idea to this plugin based on a similar WordPress plugin "SEO Friendly Images" by Vladimir Prelovac. This plugin version has more settings, possibilities to configure your »alt« / »title« attributes and it’s actively maintained. There is also a sync function, that automatically use existing »alt« as »title« and vice versa if one of the values exist. This is really important, if you have already optimized some of your images.
