Worry free, but…

The free version itself is great if you don’t require per-file basis control. In that case it works as expected. Just make sure the media files you upload have good titles, otherwise you can end up having lots of filenames like “canon-digital-camera.jpg”:)

What i also like about the plugin is that it gets rid of latin-ext (and maybe other) characters that can cause problems in Safari browsers (WordPress core itself still has filename sanitization problems with non latin characters).

The pro version is also easy to use and provides more settings and per file editing options. Worth the money:)
