Irfan View by Skiljan Irfan

I've been using this viewer for years and wouldn't use anything else. I've tried others and remove them and return to Irfan View exclusivly. This freeware program is probably as good or better than most viewer software. Adding the available plug-ins makes it even better. It can view any type graphic file you desire. It's the best!

This tiny software is wonderful! You can resize pictures, touch them up change the color and view all types of gif, jpg, bmp and tons of other extensions

If all the bloated, exorbitant, and user-hostile software i've had the misfortune to buy worked as well as this sleek little FREE graphics viewer i wouldn't be considering junking my computer [seriously].
The latest version isn't as fast as the preceding one so if you have a slower machine you may want to seek it out. Otherwise, you're gonna love Irfan 3.8. Be nice if he added identify-duplicate files [sort by file size can be fooled by any change], and added [more] video codecs [but this latter is epidemic among video viewers of course], but i'm embarassed to pick at this fine product.
There may be better products in this category but i've not found it. Just get it [and thank Mr. Irfan!].

PS: The slideshow feature is a bit clumsy [there should be a recognize-current-directory, so instant slide-showing possible]. But i'm through looking free thoroughbred horses in the mouth!
