My ViewPad (Version: 4.1.0 build 16212 tested) is a freeware image or graphics viewer that is also available for Mac and Linux. It supports over 100 formats, many of them both read and write. These include the common .jpg, .psd, .tiff, .raw, .ico and .gif formats to less common ones like .tga (Targa), .wmf (Windows Metafile), .pict, .psp (Paint Shop Pro) and others.
The interface is simple and straightforward. The image area includes right click support for Copy, Rename, Delete, Properties, and somehow oddly Open With and Preview. The latter two are for opening the images using another image viewer and Windows’ own picture viewer.
The menus on the right hand side of the program window are as follows:
File menu features Open, Reopen, Open Recent, Open Image Folder, Next Image, Previous Image, Save, Save As, Save As Wallpaper (centered, tiled, stretched, fit and clear desktop), Print, Acquire and Delete Image.
Info presents basic info like path, size, dpi, (jpg) mode, color space, compression and similar info depending on the image format.
Edit features Undo, Redo, Flip, Rotate, Scale, Crop, Color Corrections (Gamma, Brightness, Contrast, Auto levels and Auto contrast), Copy, Copy Full Path, Paste, Clear and Change Checksum.
View features Zoom in, Zoom out, Actual size, Best fit, Full screen and EXIF or Page options relevant to the various formats.
Tools includes settings and associations. The former features Rendering quality and Raw interpolation, among others. My ViewPad should run on all Windows versions.
