Generating product images with AI: a workflow that holds up at catalog scale

Generating product images with AI: a workflow that holds up at catalog scale

Photos are one of the most expensive line items when launching an eCommerce store: the photo shoot, post-production, and every new SKU starts the cycle over again. Generating product images with AI can cut these costs, but there is a huge gap between producing one nice image and sustaining a catalog of hundreds of SKUs with a consistent style. In this guide we walk through the workflow we use in the projects we manage.

What AI can do with product images (and what it can't)

The starting point is a clear limit: the product you sell has to stay the real one. Color, proportions, materials, labels. If the generated image alters them, the customer receives something different from what they saw on the product page, and you pay the bill in returns and negative reviews.

That's why the workflow we recommend to our clients almost always starts from a real photo, even one taken in-house with decent lighting, and uses AI for everything else:

  • background removal and replacement;
  • realistic settings (the vase on the wooden table, the bag being worn, the jar on the kitchen shelf);
  • seasonal variants of the same scene for campaigns and social media;
  • cleanup and retouching: dust, reflections, small imperfections from the set.

Generating the product from scratch makes sense for mockups, concepts and internal materials. For published product pages, the base must be a photograph of the real object.

The workflow for generating product images in batches

A catalog rests on repeatability, not on the inspiration of the moment. In the website and eCommerce projects we manage, the workflow is this:

  1. Define the style once. A short guide covering lighting type, camera angles, palette and permitted settings. Two or three approved reference images become the benchmark you compare everything else against.
  2. Write prompt templates, not one-off prompts. A base prompt with variables (product name, material, scene) to reuse across the whole category. That way the fifty images in the kitchen line look like each other instead of looking like the work of ten different photographers.
  3. Generate in batches by category, not in random order: style outliers stand out immediately when the images sit side by side on a grid, far less when you look at them one at a time, days apart.
  4. Name the files with the SKU from the start and keep the prompts and settings used for each batch. When you add ten SKUs six months from now, you pick up from there instead of starting from zero.

Point 4 is what separates a workflow from a series of experiments: if you don't know how you got an image, you can't reproduce it.

Visual consistency is the hard part

Anyone can generate a pleasant image. The problem shows up at the twentieth: the lighting changes, the perspective drifts, the tones warm up or cool down. On a category page these differences add up and the store looks improvised.

A few practical habits we rely on:

  • work with reference sets per category and always attach the sample image when the tool allows it;
  • fix the same proportions and the same crop for all product pages (for example square for grids, horizontal for hero images);
  • do the review on a grid with all the images from the batch together, never one at a time;
  • if an image comes out well but off-style, discard it anyway. A consistent catalog sells more than twenty beautiful, disconnected images.

Quality control before publishing

Every image that goes online passes through a checklist, no exceptions:

  • Product fidelity: direct comparison with the original shot on color, shape, details, label text.
  • Artifacts: hands, reflections, background text and inconsistent shadows are where generators fail most often.
  • Format and resolution: the image must match the dimensions expected by the theme or the CMS, so it isn't cropped or stretched on the page.
  • File size: export in a modern format and compress before uploading, because the product page has to stay fast.
  • Alt text: describe the product, not the generated scene. It matters for accessibility and for image search.

Human review must cover one hundred percent of the images, not a sample. An artifact on a product page costs more than the minute it takes to spot it.

Licensing and transparency

Before putting a generation workflow into production, read the terms of use of the tool you've chosen: check that commercial use is allowed on your plan and what the platform says about ownership of the outputs. Always keep the original product shots: they are the proof of how things really are and the base for regenerating everything if you switch tools. And where the context calls for it, disclosing that a setting is reconstructed is a safeguard, not a flaw.
