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."
