tiff

Six TIFF images from 160x120 up to 1920x1080 and 1080x1920 portrait, from 3 KB to 55 KB. TIFF is a flexible format used in printing, scanning, photography and medical imaging. Browsers cannot display it, so a web page needs to convert it before it can show anything. That makes it a handy check for upload systems: it should accept the file, then produce a viewable thumbnail in a format like JPG or PNG. Use the set to confirm that conversion works at every size, and that your code fails politely if TIFF is not supported.
