Small image size, must pay

The plugin works BUT…
The images will pop up but will be less than 800 pixels in width, so are forcing your large images to be… not large anymore.
To change this setting, you have to pay for a premium version. The description page says nothing about premium plugin and the description actually says:

The plugin gives the ability to:
Change it’s form, color, size.
Set one from wonderful 5 views, that you can change and see from General Options.

So this is basically a lie because you cannot do these things with this plugin.
