Image Editor Overview

Merchinary Image Editor is a Shopify app that lets print-on-demand (POD) stores bulk-edit layered product images while keeping every variant↔image link intact. Instead of opening Photoshop once per image to swap a background, a print, or a logo and then re-uploading and re-linking everything by hand, you build a filter to pick your products, edit images as a stack of layers in a grid, preview the result, and apply the change across the whole set — now, on a schedule, or on a recurring schedule.

Full walkthrough of the Image Editor — scope, layer grid, asset library, previews, scheduling, and revert.

Who it's for

The Image Editor is built for print-on-demand t-shirt and apparel stores whose product images are composites — background + garment + print design + logo + badge. It assumes your layer images share a fixed canvas and alignment. It is not a general-purpose photo editor or background remover.

What makes it different​

Most image apps on the Shopify App Store either run pixel operations (resize, background removal, AI restyle) or generate brand-new mockups from blank templates. The Image Editor does neither — it manages and refreshes the images you already sell:

  • A shared, cross-catalog layer-asset library — store a background or logo once, reuse it across many products and edits.
  • Layer-based bulk swaps — change "Layer 2" (e.g. the print design) across hundreds of products in one action.
  • Bucketed dedup — composite once per color (not per size) and attach to all matching variants, mirroring how POD images are actually produced.
  • Scheduled & recurring edits — launch a seasonal background on a date, or add a weekend-sale badge every Friday, with automatic revert.
  • Snapshot revert — every apply captures the previous state, so you can roll back exactly.

How it works​

  1. Install the app and complete the one-time data sync (shared with Bulk Product Editor) so your products, variants, and media are mirrored locally for fast filtering and previews.
  2. Open Bulk Image Edit from the app sidebar. You land on a single page that mirrors the Bulk Edit page.
  3. Set your scope. Build a filter to choose the products to edit, pick the dedup dimension (usually Color) and the layer count, then Apply scope to freeze the set.
  4. Edit the layer grid. Each row is a product (and its variants); each column is a layer. Fill cells from the Asset Library or by uploading PNGs, or use a column swap to set one layer across every product at once.
  5. Preview. The Next Image column shows a live composite as you edit; open a per-bucket preview for a larger view or an exact server-rendered composite.
  6. Create the job. Apply now, schedule it for a date/time, or set it to recur — with an optional auto-revert.
  7. Track & revert. Every apply has a results page with before/after for each product, and a one-click revert within your retention window.
