Icon upload for Pages plugin

hello everyone.

I'm not sure if this is correct place to post this, if not please move to appropriate group.

I'm on the mission to add icon/image upload ability to Pages plugin so it is displayed like it is on Groups plugin.

I searched community but nothing showed up. I looked at the Item Icon plugin (http://community.elgg.org/pg/plugins/project/384586/developer/dramirez/item-icon) but documentation is not very clear.

Has anyone ventured into this with success or can point me in the right direction or share any tips it would be greatly appreciated :)
