Watermark for Joomla Site

I recently purchased a Watermark program called Watermark for Jomsocial. It lacks in functionality. I need this plugin to have added functions: 1) I need to be able to assign different 'sets' of watermarks, based on different criteria. Such as: User Permissions All users & all groups All users Covers from all users Displayed user All groups Covers from all groups Displayed groups Specific albums Specific users Specific groups 2) Need watermark to show the same size no matter the orientation of the image it is on (landscape vs portrait) Plugin can be found here: [login to view URL] Program already does most of the work. So I'm not looking to pay a lot more for this. Something under $75.
