cute but not working

I’m not used to give 1 stars but this time I must as the plugin absolutely doesn’t do anything.
First, it should be nice to have a “start optimizing” button. Second, it’s good that nothing is stored on the database but this means that on deactivating/deleting the plugin all alts/titles will be deleted. Third, all that is something I assume because, as a matter of fact, once I saved my options no alt tag was added to any image. Seriously, it didn’t even keep my custom alt attribute in the options dashboard.
Too bad. No need for an investigation, I have no time for that. Thank you anyway for offering your product.
