I have a client's website http://australianequipmentwholesalers.com.au/2007-jcb-8014-cts-1-5t-mini-excavator-with-three-buckets-less-than-1500-hours/
The website has been built and has products on it. As you can see there is a photo section listing the product images with a zoom effect.
To load images is very time consuming. We must add 1 image per time via Add Media > Copy the image URL > Create a Custom_Field on the product page > Paste the URL and then repeat.
A developer to add a plugin or feature that can be used to add a photo gallery of the product, via the product edit page.
