This Xlarge Icons icon is a responsive icon. This means that it's optimized for four resolutions, from tiny 16x16 until highly detailed 80x80. The style comes from the latest Microsoft Office, which makes it perfect for any Windows applications, in particular, those with ribbon toolbar control. Unlike other icon packs that have merely hundreds of icons, this monster icon pack contains 15,300 icons, all in the same style and quality.
This looks like an image icon on Microsoft Windows. There are 2 rectangles, one inside the other slightly smaller to create a picture frame look. Inside is a jagged line to represent a mountain range and a small circle above this line looks like the sun or moon.
