| 52 | <p><i>thumbnail</i> is a program written to show how one | |
| 53 | might use the SubIFD tag (#330) to store thumbnail images. | |
| 54 | <i>thumbnail</i> copies a <small>TIFF</small> Class F | |
| 55 | facsimile file to the output file and for each image an | |
| 56 | 8-bit greyscale <i>thumbnail sketch</i>. The output file | |

| 58 | full-resolution page linked below with the SubIFD tag.</p> | |
