There are lots of image viewers out there, most of them freeware. While ones are quite sophisticated and powerful as ACDSee and IrfanView, giving the user some image editor features and slide show generators; others keep to the core - viewing images. FocusViewer is a good example of a basic image viewer.
     FocusViewer is a tool that lets you view images stored on your hard disk or removable media. It has a familiar, one could even say predictable, interface with the main window divided in three areas: the disk explorer area, the image view area and the thumbnails area. As you browse a folder on your disk, all readable images are displayed with their thumbnails and info on their type, resolution, date etc. The range of supported image types is quite impressive: from BMP to CUT. There are basic file manager functions - you can copy and move images between folders.
     There's one very useful feature: you can save all thumbnails of your images. Otherwise the program is pretty basic, and you should use it only if you don't need any advanced features but plain image viewing.
