Here's a simple to implement trick that will save you a little bit of time if you want to review all of your products photos in a Shopify store.
If you want to review all of your store's product photos, there's no built-in way to do it. But here's a simple bit of liquid code to put all of your product photos onto one page.
To get this to work, create a new page template and the liquid code below to the page's code. Then create a page that uses that new template. Viewing that page will list out all of the products in the store. Each product title is linked to that product's page in the admin, so you can easily edit. Under each product, all the product's photos will be shown.
Here's the code for the product page. You can place it where ever you want. Just add the code to the product template or section that contain where you want to place it.
You can edit the code to meet your specific needs. One thing you change is the size of the photo shown. The code above is using Shopify's 'large' size. You can replace that with any size you want. You can also change the 'all' to specify a specific collection you want to see listed.
I hope that helps! Let me know if you have any questions.
