Image Tiling Preview Tool

This neat JavaScript tool generates a repeatable pattern preview of any image you upload. This is helpful, for example, when you are designing a seamless pattern and have no other means to view it in action. Select an image then click "Generate Preview". The tool interface can also be hidden by clicking "Interface Toggle" button in a top left corner and restored back the same way. To access the tool follow this link or click the image on the left.
