Resource groups in S3PE

IMG

These are located in the .nhd and the TravelDB.package files. If you shred them all you could lose stuff. Best to go through manually and select the ones you want to delete. Oh, and deleting them in-game doesn't delete them here, apparently.
If you want to go nuclear but keep the ones that matter to you, or if you've got way too many of these darn resources and it's going to take too much time to clear out, follow this guide.
If your Sims travel, get ready for a wonderful glitch: the game will save IMGs normally only located in the TravelDB.package file in both that and the .nhd file! If you travel frequently, be sure to delete from these files regularly.

• 0x0269D005: memory snapshots, camera photos, still life, and portrait paintings.
• 0x024B9FCA: seasons greeting card photos
• 0x02722299: prom pictures

The others are... I have no idea what the heck they do, but probably best you didn't touch them...

SNAP

These are located in the .nhd file only. They mostly consist of Sim portrait poses and thumbnails that are generated by the CAS system every single time CAS does something, and the game will never reuse existing resources, so it'll just build up in this file, slowly increasing load and save times until the game chokes on itself and you get wonderful save/load game errors.
You can just go nuclear and delete all of them. You may notice some lag as the game regenerates the SNAP resources that it really needs, but that should clear once it's done. See [1] for more details.

• 0x00000001, 0x00100000, and 0x00100001: Sim portrait poses (And good grief, do they build up; the game doesn't reuse old resources so it'll just keep generating new ones!)
• 0x00200000: smaller Sim thumbnails, presumably used when the change clothes dialog is open
