Preview 162+ image formats from Explorer context menus

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

This means that, once the program is installed, you don't have to double-click an image to view it any more. There's no need to have the Preview window open, either, or to switch the folder to Icons view. Instead, just right-click the image name, select SageThumbs, and a thumbnail of the image appears, embedded in the context menu itself.

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. The email and conversion options work with multiple images, so you're able to process an entire folder of photos all at once.

SageThumbs also has plenty of configuration options, including the ability to make image previews just as large as you like. This worked for us, but beware, if you're processing very high definition images then Explorer may slow down considerably.

Version (Full Changelog)
◾ Added Dutch translation (by Gaston Loos)
◾ Updated Italian translation (by Marcello)


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. Still, most of the time we had good results, and the XnView library it's based on is solid and reliable. Worth a try if you like the core "preview in a context menu" idea.

Windows 10 May 2019 Update ISO (build 1903)

Free Full Commercial Software

This is the latest version of Windows May 2019 Update. it's a media creation tool that can be used to upgrade an existing installation of Windows or create installation media for another PC. Just make your choice after launching the tool and it'll do the rest.

What was new in Windows 10, when it was released? The OS brought back the Start Menu, though with a twist: live tiles keep you up-to-date with the latest news while also providing an easy way to launch apps. (Don't worry if you prefer the Start Screen, it's still there and you can boot into it if you prefer.)

Apps now work much more like regular desktop programs. They have minimise, maximise, restore and close buttons, and can be resized (to a degree) and organised however you like.

If you've still lost track of a program in the mass of open windows, a new Task Spaces feature can help. Click its taskbar button and you'll see thumbnails for everything running now, a little like OS X's Mission Control - just click something to switch to it.

Better still, Task Spaces also supports virtual desktops. Add extra desktops as required and it'll display thumbnails of each one, making it easy to identify whatever you're after and switch to it.

There's also smarter snapping, new customisation options, and even a bunch of experimental additions to the command prompt.

May 2019 Update brings a whole host of new features for Windows 10. See the Microsoft Blog for more information.

The Windows 10 ISO will give you build 1903 which is the May 2019 Update.
