What is a PNG?
.PNG is our standard. P.N.G stands for Portable Network Graphic. It's the native file format for popular programs such as Microsoft Office, and Adobe Fireworks. More importantly, it can support lossless compression, 48-bit, true-color depth, with varying levels of transparency. It's a perfect fit for us.
Not all of our isolated stock art will have a transparent background. The Artist may isolate the subject with lighting or other techniques. Look for files with a checkered background, which indicate the image has a transparent background!
