Plone Archetypes framework already gives you a max size validation for files and images, but the default configuration has some drawbacks:

• is not simple to customize (best way is to use plone.recipe.atcontenttypes)
• is the same for every Plone site of the environment

This product will let you customize this validation from Plone user interface.

Just add the product to the buildout and install it in the site you want to use.

A new "Limit file size settings" option will be added in the control panel, where you can change the File and Image attachments.

No users will be able to upload files that exceed the limit.

If some users need to bypass the validation and upload some larger files, there is a new permission "collective.limitfilesizepanel: Manage limit file size settings" that allows to do this.

You only need to set this permission to some roles, and they'll have no upload limits.

This products has been tested on:

• Plone 3.3
• Plone 4.2
• Plone 4.3

It's based on plone.app.registry__ that it not part of Plone on 3.3 version. You need to be sure that a compatible version is used (in my experience: use version 1.0b1__).
