Understanding your result
Twelve images arranged in four columns form three rows of thumbnails. A contact sheet helps you review the set at a glance, but each small tile holds less detail than its source image. Keep originals available when checking focus or reading small text.
What to do if you have a problem
If tiles are too small, raise Thumbnail width or use fewer columns. If generation exceeds the pixel limit, reduce thumbnail width or the number of selected images. Click Process images after changing Columns, then inspect the PNG's labels and image order before saving it.
What to know before using the result
Each tile shows a still-frame thumbnail. Large contact sheets are limited to 16 million pixels.
