"Thumbnails" are small images that act as an icon or preview for a piece of artwork or a folder on your website. These little images are displayed in a grid to give visitors a quick summary of what you have for them to see.

Your OtherPeoplesPixels website helps you automatically create a thumbnails for each images that you upload. After you upload a new image, you will be taken to a screen with your image on it, where by clicking and dragging the red box, you can define the 100x100 pixel square that will be your thumbnail.

You can also create custom thumbnails for any piece. For example if you want to make your thumbnail a box that says 'Paintings' or a picture of something other than the artwork you uploaded. Read Making Custom Thumbnails for more details.
