Oct 11, 2017 - Open All Images Into a Single Preview Window on Mac OS. Open the Preview app in Mac OS and go to the “Preview” menu, then choose “Preferences” Under the 'General' preferences tab, look for “When opening files” and choose “Open all files in one window”.

JustLooking is a free and amazing image viewing program for OS X with a cool interface. One can quickly see many pictures in one go using the left/right key and view numerous images automatically using its Slideshow feature. It has various customization options, users can rotate, Zoom In/Out, Resize images, view images in full-size using Command + 1 shortcut and get detailed info of desired images. Set it as the default image viewing application instead of “Preview” for opening most image file formats!

It converts the XML code to a readable format. Readers can be web-based, browser-based, or in the form of a downloadable app.

Features: • It focuses on files and directories instead of lists of files. Thus, once you load a file, you can easily navigate through all other files in the same directory. • It displays images at their native resolution instead of interpreting DPI information stored in the image meta-data. While images are printed at the maximum resolution possible, on screen they are displayed pixel-by-pixel.

• Being designed more for viewing of Images, it properly shows animated GIF files. • The entire program can easily be manipulated and powered by simple keystrokes for a quick and pleasant viewing experience. • There is support for printing, image resizing, saving to a few key image formats, and displaying of all image info.
