Issue: When preview images are displayed in Review / Validation page, the image isn’t clear in IE browser compare to other browsers such as Google Chrome, FireFox and IE Edge.
Root Cause: While resizing in IE, the down-sampling algorithm throws away neighboring pixels leading to loss in quality. Chrome/Mozilla handle this resizing differently, using smarter algorithms, therefore the image is sharper in those cases.
Solution: Use shortcut key Ctrl + Shift + D (Pop Out Image) to pop out the preview image into a new window.
