 		PhotoQt is a fast and simple, good looking, yet powerfull and highly
 		configureable image viewer.
 	</p>
-	<p>
+    <p>
 		It provides an uncluttered interface and can be extensively tweaked
 		to fit your needs perfectly. It is possible to set key or mouse shortcuts
 		for almost any one of the features, plus for any external script/command
 		you want to run.
 	</p>
-	<p>
+    <p>
 		The many features provided include: thumbnails, slideshow, zooming, rotating,
 		flipping, displaying metadata (selection of Exif and IPTC), set-as-wallpaper, simple
 		file management, scaling and more...
