Well, yeah...it's not free...and it's not worth 20 bucks US nor is there an option to buy software through Paypal.
It's buggy.
The trial has a big, ugly watermark.
And worst of all, the program has 0 options to choose & display image attributes (ie, dimensions, colour depth, resolution, how many frames in a gif file, etc.) I would have liked seeing that other than a huge waterwark saying trial all the time
Also, I have and use regularily a context menu viewer...mPower Tools from ACDSee, the company notorious for ignoring their customers. Awesome software though.
