Various fixes customized oscommerce

I have a highly customized oscommerce website that needs a few fixes listed below: - auto select inseam size, and any other future attributes that will be created. see: [login to view URL] - when loading product page have the image load right away instead of loading regular image and then dissappearing and then loading the color image. see: [login to view URL] Notice how the page loads without any default values selected, and therefore once the value is automatically selected it also reloads the product image. - image zoom on multiple images not working properly. a) [login to view URL] zoom is cut off on bottom, cant see bottom of pant. Zoom works perfectly on products when only 1 image and only 1 color see: [login to view URL] But also does not work when there is 1 image and more than 1 color it gets cut off on the bottom. See: [login to view URL] b) when changing between images, can you make the fade transition a lot smoother. See this product page: [login to view URL] - image zoom on mobile, use mobile jquery or load a different zoom plugin for mobile use if necessary. - promotional price of product has to show on product page. the price is correct in shopping cart but dissappears. see: [login to view URL] note the promotional price works correctly when adding to the shopping cart - have credit card type show up in admin on order page. using [login to view URL] module. would like to see if VISA, MC, or AMEX. should automatically detect based on card number. Just want to be able to see what card was used in order admin.
