XV thumbnail
From Just Solve the File Format Problem
XV thumbnail, also known as XV Visual Schnauzer format, is an image file format used by the XV image viewer for its thumbnail cache. The color format is 8 bits/pixel RGB 3-3-2.
Thumbnail files are normally written to a subdirectory named ".xvpics", and evidently use the same filename and extension as the full-size image file. The .p7 extension might be used artificially sometimes, if such a file has been moved out of the .xvpics directory, or created by other means.

Identification
Files begin with ASCII text "P7 332
", followed by a newline.
Note that they could easily be misidentified as PAM format.
Specifications
The format is described in a "THUMBNAIL FILE FORMAT" comment in the xvbrowse.c file from the XV source distribution (v3.10a, at least).[1]
