How many pictures can be posted on the same posting?
2If it's for set identification, we only need a couple provided they are detailed enough so we can identify key elements...– Michael VerschaeveMay 30, 2022 at 22:04
There's no real "technical" limitation, however you should be considerate of users bandwidth and time.
If you're trying to identify a set, a picture of each bag, or enough pictures to show the key "unique" parts is sufficient, an individual element probably only needs a single image unless there's major features on different angles.
If you can crop the images to show the relevant parts, that would be ideal.
