Integrate Bulletproof php upload class with osCommerce

I would like you help with integrating Bulletproof php upload class in my osCommerce store. I believe needs to be integrated in two places in addition to the files being added to catalog/includes/classes... First, I have already installed Option Types which has it's own upload class. I would like to use Bulletproof instead. Second, I would like you to integrate Bulletproof with Croppic. I expect you will already be familiar with osCommerce and Option Types and the code in [login to view URL] where Option Types initiates it's upload class. Croppic calls two php files ([login to view URL] and [login to view URL]) and I think Bulletproof can be integrated in one or both files. I have already set up a dummy store with Option Types and Croppic installed for you to work from. I will provide FTP credentials upon beginning the project. The relevant documents can be reviewed here... [login to view URL] [login to view URL] I do a fair bit of php programming and I believe this is a pretty simple integration. I prefer to do my own work but because this is for security I want to know 100% that it's done correctly by an expert. As far as I can tell, integration of Bulletproof seems like a good idea for better upload security... In the case I am wrong or missed something, please indicate why Bulletproof isn't right for increasing site security related to user file uploads and your proposal for a better option. Thank you and I look forward to working with you!
