How do you fully control picture input size of picture and frame?

[Nic Brough -Adaptavist-]

For input, you can't do a lot - you are allowing your users to attach files, and that's about it.  You can limit the size of attachments, but that's not a huge amount to do with picture size.

In the display-picture macros, you can frame images at a certain size though.
