Help needed with testing my application

Question

Hi guys,

I am not sure if this is the right place but I will try anyway :P

I have created simple desktop application for resizing and converting images and I would love to hear your opinion.
The application can be downloaded here: http://www.softpedia.com/get/Multimedia/Graphic/Image-Convertors/MAQU-Image-Resizer.shtml

I am working on the new version now and some new ideas/comments would be most appreciated.

Thanks,

marqs
