Now we're only missing the Soldier, Demoman and Pyro. I don't suppose it'd be worth creating a pool for these five pictures?

Sorry for the sudden danmaku of questions; I normally translate more than I upload and tag.

Not a pool, parenting will suffice. Just copy the post number from the URL of one image (since there's no real order to these, it doesn't matter which one) and paste it into the "Parent Post" box of all the others.

I made the same question some time ago in the forum and the answer was to create a pool.

Parenting makes sense in cases where one or more images is/are related to a particular main image (the parent). In this case, no parent can be identified – they are all peers – which, to me, says pool.

It's probably better to group them in a pool than to leave them like this. If people don't like it, it can always be deleted later.
