The invention relates to a picture compression and thumbnail reuse method and device and embedded terminal equipment, and belongs to the field of image processing. An operating system application can generate a thumbnail corresponding to a picture in a photo album for the picture; the method comprises the following steps: compressing a picture through a compression service process running in real time, recording initial time t0 when the picture is stored, and after a post-processing file and a data file are generated, updating a last modification time parameter of the post-processing file to t1; calling a system calling function for setting file time to modify the last modification time parameter of the post-processing file into t0; and updating data in the database of the framework layer according to the last modification time parameter in the post-processing file, and calling the thumbnail stored in the system through a picture library matching check mechanism. According to the method and the device, the ti
