PICT, or QuickDraw/PICT, is a complex graphics file format used on Macintosh computers. It is associated with the QuickDraw API.
Though it is a vector format, it is often used as if it were a raster format. Many files contain just a single bitmap image.

Identification
Version 1 PICT files have (hex) bytes 11 01 at offset 522.
Version 2 PICT files have bytes 00 11 02 ff 0c 00 at file offset 522.
Custom data
Custom application data is sometimes stored in PICT files by using (abusing?) the "LongComment" opcode. Comment "kind" 224 is used for ICC profiles, and kind 498 appears to be related to Photoshop.
