I have been using Picture Viewer Pro as a direct replacement for a certain long-in-the-tooth image viewer on the PC for some time now...
Updates have been thin on the ground. 15 months to be exact... then bang! Out come two within 24 hours!
Picture Viewer Pro was built for a purpose to do a specific job and to do it well..
It is fast, small, light on resources and has no bloatware features in it, unlike some of its competitors products!
It's basically an image viewer with some interesting info bars - showing EXIF info etc. Very handy for photographers.
I like it most however, as you can use your mouse wheel to quickly run though loads of JPG's!!
If you want to know what Picture Viewer Pro can do for you, then please take a look at their website...
The free trial verison, which is slightly crippled is below.. but I noticed they are still offering a lifetime license at the special price of just Â£7.50 at the moment!
