Good Afternoon,
I'd like to preface by saying that I haven't done any development for Shopify in the past, and this is mostly looking to ensure that what my client is asking for is even possible. I've poked around your API documentation, but everything I've seen so far doesn't appear to allow me to modify your administration panel or pre-existing templating variables.
Essentially what my client would like is the ability to upload image assets and tie them to their collections. These images would be separate from the collection's products, as the images are to be used in a rotator to show off the collection itself. Ideally, this would be managed in the admin panel underneath the product management section with the same features built into it for management purposes (sorting, Add Images, etc). From there, the image array would need to be accessed in the template via a {{ collection.imageGallery }} variable to then render it to the page.
Is such customization of your content management system viable with the tools provided? If so, could you point me in the correct direction?
My most sincere apologies if this information was readily available and I just happened to miss it in my perusal, and thank you for your time,
- Kyle Duke
