It is an image of a man standing at the edge of a ledge next to water. He is bent over with his hands out in front of him towards the water. The image has a slash through the man seeming to mean no diving into the water.
This No Diving 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 15,900 icons, all in the same style and quality.
