You want to see your images in a preview? Extra big? Then you are exactly right here!
With DoublePics you may move yourwindows to the desired location on the surfdace location - even on a separate screen! Thus, you have an entire monitor for your preview and you are able to go on working with the program regardless of the other monitor.
In the preview window, you do have further options, such as an 8x zoom, or a change in quality for images.
