Image cut outs (100 images)

This project is to process a number of images in photoshop for our website and catalogue. it is difficult to say exactly how many images there will eventually be so we will manage then in batches of 100 images. I suspect we will have 500 -1000+ images to process when the project has been finally completed. the images will be two main types: 1) Product Images a product shot on glass with a green background - the actions required are; cutting the images out (this must be done accurately with care … not "rough edges" using the lasso tool !) there may be a little clean up required on the product to hide any imperfections. 2) "Cut away" photo's - here we need to make a "Master cut away image" (see example) where the edge looks Perfect. Then for each of the different products we need to cut out the "insert images" so that we can drop them on the "Master image" - a cut out layer from the master image may prove to be a timesaver here. The animated gif shows what we are trying to achieve. We have set up the camera so that there should be little to no deviation between them
