If you just want to see one piece, go to Edit and scroll down to see whether tote bags is available. If it is, put in a price. Submit. That should do it. You may have to refresh the page to see that the tote is now available.
If you decide you want to add totes to all your images (providing the files are big enough - I did notice one of your pieces is only available as a card which may be your choice or may be a file size issue), you want to do two things.
1) Go to behind the scenes, look for Bulk Edit, show and select all your images. The first thing that comes up selects only all the images on one page. If you have more than that, there's a little box under that which allows you to select all your images. Now Edit Checked Images Simultaneously for Tote Bags. Don't forget to hit Submit when you are done. This will get all images that you already have uploaded.
2) Now go to Behind the Scenes > Default Settings and put the same prices in for totes. This will catch any new uploads that you do.
Hope this helps.
