How can I move my add cart button in the product info page?

How can I move my add to cart button from the bottom of the image to the side of my image right under the Unit Qty?

Also when you click on "Larger Image" pop up image is way to big. How can make it smaller?

hi
See this thread , more or less, it's about the same.

That doesn't show me where I can change my image size for the popup image for the product image.

There is no resizing of the "large" popup image - ZenCart just uses the actual image size what ever it is

To have better control over the larger image size instead of resizing all of your product mages independently, there iis a program called image handler version 4 (IH4) that will offer the ability to downsize the larger image. Please search the plugins area, then review the instructions and the forum thread. There are very few if any issuues not already covered in those two places.
