Thumbnails

Create thumbnail of image too

None of the other options on this page will have any effect if this checkboxis not checked. By default, it is off.

Thumbnail size

This is the percentage of the original's size that the thumbnail will be. The default is 25%.

Thumbnail compression

This is the quality of compression to use. As with the general preferences, the better the quality of the compression, the more detail will be preserved, and the bigger the thumbnail will be. The default for a thumbnail is 50%.

Prefix to attach to filename

This is the prefix to attach to the thumbnail filename to distinguish it from the full-size shot. If you leave this blank, the thumbnail will overwrite the full-size shot and you will lose the full-size one. The default prefix is "thumb-".

Use high-quality intermediate for generating thumbnail

This checkbox is off by default. It generates a MIFF image whilst making the thumbnail. A 'lossy' file format refers to a file format where data and detail is irretrievably lost, but which is typically much smaller than a non-lossy format image of the same thing. The typical example of a lossy file format is JPEG.
