Shopify Updates

Hi I have a shopify site, [login to view URL] and have a a lot of images added and a product personaliser. I have 6 mock up templates of which all photo's can be selected or chosen to update within the the mock view with with the image chosen. I have a few jobs. Current Images Update - Product Personaliser 1:) I would like to add many more images to the product personaliser for people to choose from many more products in my store. New Gallery App Look book shop 2:) I have started adding a gallery to showcase "look books" of products within different categories, the products have been uploaded and only 1 sample product has been populated with the correct prices, these prices will need to be copied across to all the other products . I'd like different look books to be created split into "Landscapes" "Animals" "Beach" "Flowers" From this look book the purchase drop down to buy a size canvas and price will need to be styled. I'm not sue if we should be using a different app like the Robin Pro image gallery 3:) Because I use a supplier to do all my printing all my orders get pushed through to him, ie they get duplicated so his automated ordering notifications do not get pushed through to my site, to circumvent this for now I've downloaded an app where i can manually update order status but I need a mail template built in the same styling as in my notification settings. 4:) Finally - I'm trying to sync product orders with my supplier - I've downloaded Syncio (and it looks like I"m the destination and he is the source) I'm not sure it's the correct way, I've tried t swap around but having difficulty - I've reached out to Syncio for help too.. this is just back ground knowledge.
