SageThumbs is a powerful shell extension allowing to preview enormous amount of image formats directly in Windows Explorer by using Pierre-e Gougelet's GFL library (XnView's author).

Please read carefully the following information:

As SageThumbs is a Windows Explorer context menu extension, there is no an executable file that you should launch to bring it up. To use it, just open any folder with image files in Windows Explorer, and then right-click a file you want to preview. You'll see the thumbnail immediately in the context menu.

System Requirements:

* Windows XP/2003/Vista/2008/7/2012/8/8.1 32/64-bit
* About 5 Mb of disk space + additional space for cache

Features

  • Extended thumbnail image view of Explorer folder
  • Image preview in Explorer right-click menu

  • Support 162 image formats (224 extensions) via GFL Library
  • Support additional 26 image formats via XnView plugins (if installed)

    Working nice for psd files. That's why what I needed for. Thank you so much 😄

    I'm a huge fan of SageThumbs, but recent crashes and a decade without updates forced me to right this injustice... ⚡【 THE REBUILD 】➔ After a week and an embarrassing amount of tokens, we now have a ground-up, rust-native alternative supporting 316 formats. It has zero dependencies, extensive red teaming, and is obsessively optimized for speed/size, a streamlined UI, menu editors, color picker, and screenshot tool. 🛸【 SAGETHUMBS 2K 】

    Works great for viewing HDR thumbnails, though would be nice for it to support EXR.

    Doesn't work with GIMP. Tried using its repair utility, same result.
