Super plugin and support
by cosiek·1 month ago·1 reply
I wanted to highlight the great support. During usage of PRO version I observed some bug, which was quickly fixed by Team.
I really appreciate it and thanks to that I cleaned my disk space on server.
Thank you!
Worked Perfectly

Not sure why so many people are griping about the free version not able to do anything. Just pay the price for the software, unlock the features, and get the job done! People who write plugins have to eat too! I had to regenerate 20,000 thumbs today due to a spelling mistake in the watermark. RTA did it quick, easy, and professionally. No fuss, no crashes, no scratching my head trying to understand it. Giving a plugin one star, just because you don’t want to pay is not cool. Star ratings are for functionality, not because you didn’t get a free ride!
Predatory

Simply predatory, no need to waste time on writing anything else. Don’t support plugins like this.
Useless: this plugin can only regenerate thumbnails for free, nothing else

Useless: this plugin can only regenerate thumbnails for free, nothing else.
For all other things like deleting unused thumbnails etc. you have to pay a monthly or yearly subscription, things you can do with a code snippet for free.
free version is useless

It can’t even delete files with unregistered sizes. Useless!
