Irfan View3.98 Description:
irfanview is a freeware graphic viewer for all windows platforms. the publisher states that its purpose is to be accessible enough for a novice and powerful for advanced users. in my opinion, this goal is accomplished. when you install the program, you have the option to associate filetypes with it. there is a button for associating only images with the program which i like because usually i only open images with irfanview. however, the program has a long list of supported file formats. if you want to open even more file types you could download the plugins suite from the publisher's website.
