OSCOMMERCE admin add-on: MULTIPLE IMAGE uploads in Categories/Products section

I have slightly modified the ADMIN section of OSCOMMERCE. I need the ability to upload THREE images (instead of one) in the Categories/Products section. For example: images are named for example [login to view URL], [login to view URL] and 1030_lg.jpg. [login to view URL] is the large version [login to view URL] is the thumbnail [login to view URL] is the zoomed in version The catalog is already hooked up to images named like this... all I need are three upload buttons in the ADMIN section pointing to the right places in the images folder: [login to view URL] is already set up to go into catalogue/images. keep that the same. [login to view URL] needs to go into catalogue/images/products/thumbs/ [login to view URL] needs to go into catalogue/images/products/large/ Also... Please put a disclaimer above where they upload the normal-sized image that says: Main Product image size must be exactly 453 x 452 pixels. Disclaimer for "Thumbnail" should say: Thumbnail image size must be exactly 120 x 120 pixels. Disclaimer for "Enlarged View" should say: Enlarged View image size must be exactly 672 x 580 pixels. The names of the thumnails and enlarged views will most likely need to be stored in the database. I need quick turnaround on this. I've already started it but have no time to finish. Thank you!!!
