Hiya Tom,
The images are vague as of yet to know how to tell you what to do with them since I'm not exactly clear on what you are planning to use them for. Are they photos of your products for each of the products themselves or are you doing a photo page for them? Can you be more specific on what you plan to use the photos for?
As for the images for the products that's really easy. All the product areas are drag and droppable so you can drag and drop your images right from the folder if you have it open, or you can navigate to that folder and insert them etc.
The problem though with the product photo setup is that they do not keep the original naming of the files. SCC programs do rename all the files that it uses so that it can follow it's sequencing more efficiently. Yes I agree this is a hassle, and I too wish it would keep the original file names and just add an extension or something so you can find them easier, but unfortunately that is not the case.
The good news is that all the product pages, details pages, site pages, etc. that SCC programs create now have really nice SEO systems built in that allow you to be very creative with the SEO so your products can be found easier.
Give us a bit more detail on how you intend to use the photos and we'll see if we can help you work out a way to get that automated, but don't hold your breath on it if it's product images for the product pages you are talking about as you'll need to insert each one separately into each product. There's no way for the program to know which photos you want to go with which products. All the uploading is done for you which is pretty automated, but the footwork does remain yours.
If you are needing something outside the product pages, that might be a bit easier to work with so let us know
