Fast PSD files preview

I am looking for PSD files viewer. Gimp is too fat for this job. I need something fast and light.

You may like Kuickshow.

"KuickShow is an image browser/viewer with a nice filebrowser to select images to be shown, slideshow support and the ability to display the following image formats: jpg, gif, tiff, png, bmp, psd, xpm, xbm, pbm and eim. Images can be displayed either in their own window, as large as the image, or fullscreen (which shrinks images too large to display). KuickShow also has a slideshow mode."

XnViewMP is very good doing the job.

Download it from http://www.xnview.com/en/xnviewmp/

Nomacs is a fast and easy to use program: https://nomacs.org/

Edit: From the Nomacs landing-page its a:

... free, open source image viewer, which supports multiple platforms. You can use it for viewing all common image formats including RAW and psd images.

For simply previewing PSDs I use ImageMagick - fast and displays them properly. Also it's free and available via apt.
