nomacs is 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.

nomacs features semi-transparent widgets that display additional information such as thumbnails, metadata or histogram. It is able to browse images in zip or MS Office files which can be extracted to a directory. Metadata stored with the image can be displayed and you can add notes to images. A thumbnail preview of the current folder is included as well as a file explorer panel which allows switching between folders.

Activating the cache allows for instantly switching between images.

Since Minecraft saved games contain every single element of the world the player is playing in, it has much more in common with 3D world, map, and terrain editors than traditional saved game editors. MCEdit has been developed since 2010 with the original goal of allowing Classic levels to be played in the full version of Minecraft, but has since evolved into a full featured editor and is currently undergoing a thorough rewrite for version 2.0.
