Make sure that you are using images with the proper extension such as filename.jpg not just filename, jpg images work best for the resizing algorithm used. png and gif images may also be used. jpeg, gif and png are the only types of images that are save to use on the web since browsers don't know how to handle other types. Do not use images that have transparency, the software may not be able to tell what the transparent color is and it could change the colors in the resized image.
You can see what theme are responsive on http://www.shopsite.com/templates/cookbook/builtintemplates.shtml each theme that is responsive has a blue banner that says Responsive. Depending on which version of ShopSite you have you may have all of the theme or just some of them. It says below the theme image what version of ShopSite it was first included in.
You can change to using a new theme by going to Preferences > Themes and selecting a different theme and then publishing using the Utilities > Publish function. NOTE changing the theme changes all templates used for the site, page, product, search, shopping cart, giftcertificate etc. It may not be easy to get back to your existing look if you change the theme. Make a backup of your site (database and settings files) before you make any major changes just to be sure. Changing themes won't wipe out pages, products etc but will change the look of pages. If in doubt get a demo store at http://www.shopsite.com/demo.html and use that for testing. You can download your pages and products from your live store and then upload them to the test store. You will probably want to also upload some of your images for those pages and products and any store logos or other images you use. There isn't an easy way to copy the navigation from one store to another so you might have to manually enter that in also.
