This is the current version of IrfanView. it is really stripped down. It is enhanced by adding plugins, most of these are filters that do things to the image called "effects". Others are apps that expand the ability of IrfanView to read exotic image files. IrfanVies also updates so it is growing even now. The following thre links are to some of those. With its Pain app, this is fast becoming a rival to GIMP, without the bugs that I have seen in GIMP. It also has an extensive set of adjustable "properties". I am definitely a fan. I have used it to salvage some unbelievably horrible photos as well as create some psychedelic images

1. Plugins page. This has grown to be quite a long page as more has been added to it over time. This is a 32-bit application. I have given you the basic plugs

These are links to sites with more filters which I am not at liberty to distribute

3. Filters Unlimited. This is a premium item that includes some 350 filters and ways to create your own. Well worth the purchase price. The free version, no longer around, was just a previewer of the effect. the results could not be saved. When I tried it 7 years ago, it sold me on the program kit

4. If you want to get more out of the media player. this is the recommended codec expansion bundle
