It's packaged as a portable app, so you can view and alter your photos on the go and it's in Format for easy use from any portable device and integration with the Platform. XnView Portable is an easy-to-use photo viewer, organizer and converter. Worth a try if you like the core 'preview in a context menu' idea.A new version of XNView Portable has been released. Still, most of the time we had good results, and the XnView library it's based on is solid and reliable. SageThumbs didn't always work as we expected, with PNG viewing was turned off by default, PSDs and some of our test images not being displayed. ◾ Updated Italian translation (by Marcello) ◾ Added Dutch translation (by Gaston Loos) This worked for us, but beware, if you're processing very high definition images then Explorer may slow down considerably. SageThumbs also has plenty of configuration options, including the ability to make image previews just as large as you like.

The email and conversion options work with multiple images, so you're able to process an entire folder of photos all at once. The menu also includes a few useful image management options: you can set the target image as your desktop wallpaper, send it via email, or convert it to JPG, PNG, GIF or BMP. Instead, just right-click the image name, select SageThumbs, and a thumbnail of the image appears, embedded in the context menu itself.

There's no need to have the Preview window open, either, or to switch the folder to Icons view. This means that, once the program is installed, you don't have to double-click an image to view it any more.

SageThumbs is a Windows Explorer extension which uses the XnView library to preview 160+ image formats from Explorer's right-click menu.
