didn't wokred properly

Sorry to see that the plugin didn’t work properly, but like i said this plugin have to be tested before the use.
At this moment the plugin have one backup system, so if something goes wrong you can always came back, is important to activate the option for do some test and see if is all ok.
And you can always use dnui with other plugin, like delete all the image “not used” with dnui and regenerate the size that you want with other plugin.
But well this is part of the game of making plugin in wordpress
