Personally, I don't 'rename' images. I transfer each new image into a folder by year and location, and then an interior folder by species, or player (sports) etc. I store the original RAW and jpeg untouched, formerly on CD, but now on a SSD (and duplicate SSD). THEN, I copy a file into a work folder, and begin "playing" ... when I save the new processed images into storage sub-folders, I use the original file number, and add an '01', '02', '03 etc for each edit.
Years ago, I'd change the name to Osprey 01 or Osprey 02 when I processed each image - but then, it was tough to find the original RAW file for some other project, or take an original RAW copy for a different application ... I've found this works well, because I can at least remember generally when where a specific image was originally shot, so it's much easier to locate -- plus, the file number on each image allows a file search to find the original easily.
BTW: I use DPP directly off the camera, and then create files on the PC-SSD to initially transfer, then when the folder is complete, and labeled, I transfer one copy of each to duplicate SSDs ...
