A lot of that is actually configuration related; there is (and has always been AFAIK) an option to set maximum thumbnail size but we haven't used it.

Partly because we've talked about moving attachments entirely into the gallery but not yet done so for a variety of exciting reasons.

But the maximum size only works for attachments/sig images etc. but wont work for embbed content like youtube videos and other steaming content, or will it?

True enough. But for embedded content, I don't think you can automatically resize it since half of them need an actual size to work off.

Oh, that's a thought...

@Nao: since to do that (auto resize an embedded item to current width), you'd have to do that in the client, what about shifting the embed logic to the client side? It'd mean more bandwidth if more sites are used (but it's cacheable) but the performance saving would be enormous on the server.
