OK so I am having a difficult time starting my shop, especially with the images. You can click on the link below to view my products and you'll notice the image is very tiny where it's pretty much impossible to make out the words/picture without clicking on "enlarge image". How DO you make the image larger and clearer? (I did go to 'image help' on the website but I'm still confused).

Also, is it possible to add more than 1 image in the same category (like more than 1 image in "large pet bowl" and so on)?

Thanks.

You have a basic shop. You are allowed one of each item. If you want to put a different design on the same item type you need to open another basic shop.

For images it is best to start with using the templates until you get used to how large you need to make them.
