Black and white lion clipart from a pencil drawing, the detail of the mane (the whole picture actually) is amazing!
A very large, stylized image, the massive mane and bright blue eyes make this one look a bit fierce to me. It's also available as an SVG if you're looking for graphic for printing.
Another simple, but pretty picture of a male lion relaxing, taking it easy from the hot weather... or being lazy ;)
Here's another graphic available for download as an SVG which can be resized however massive or small you want and is perfect for print media.
This cute, glossy image of Leo the lion is also fairly large so you can resized it down to whatever size if you need.
Another simple animation, in this one the lion is moving his tail, yawning, blinking and wiggling his ears... very cute!
