Sorry for beeing inexplicit. When trying to add PNG, BMP, JPG in “Index Rules” it does not show up in the list. In version 1050 i could add it without problems.
I am also curious what is triggering the You must activate with a code to continue using the preview-function. All over the web it says this software is freeware. Seems more like trial-ware when you must either “be a student”, or share the website on Facebook (9 likes) so far?. Yeah, you know what I mean after using it for a while.
Anyway – Thanks for a great software!
