How to Build an AI Product Image Generator Workflow

How ecommerce teams batch-generate product images with an AI workflow, which models to use, and what 100 images cost on RelayMe.

Direct answer: an AI workflow for ecommerce teams

Short answer: use a workflow tool that chains a language model to an image model, so one product sheet turns into a batch of finished images instead of one hand-written prompt per photo. In RelayMe you build that once: an LLM step expands each SKU's name, selling points and target style into a complete image prompt, an image step (Nano Banana, Nano Banana Pro or GPT-Image2) renders it, and the same template is re-run for every new SKU. The batch cost is simply the per-image price added up: on the current sale tiers that is 20 credits (about US$0.02) per Nano Banana image or 100 credits (US$0.10) per Nano Banana Pro or GPT-Image2 image, so 100 white-background main images cost roughly US$2 to US$10 in model fees.

If your team produces main images, lifestyle shots and campaign assets for dozens of SKUs every week, outsourcing or manual retouching scales linearly with your catalog, while a reusable workflow does not. For one-off, hand-polished creatives, a traditional retouching process may still serve you better.

What a batch of AI product images costs (RelayMe pricing, September 2026)

RelayMe bills every image in credits, and 1,000 credits is roughly US$1. Per image on the current sale tiers: Nano Banana at 1K, 2K or 4K costs 20 credits (about US$0.02); Nano Banana Pro costs 100 credits at 1K or 2K and 200 credits at 4K (US$0.10 to US$0.20); GPT-Image2 costs 100 credits at 1K, 2K or 4K on the special-offer channel, or 200, 350 and 600 credits at 1K, 2K and 4K on the standard channel. Standard, non-sale Nano Banana is 80 credits per image. Prices change; the live table is on the RelayMe pricing page.

In batch terms: the US$19 Starter plan includes 20,000 credits a month, which is 1,000 Nano Banana images or 200 Nano Banana Pro images at sale prices. Basic (US$32, 35,000 credits) and Pro (US$90, 110,000 credits) scale that to 1,750 and 5,500 Nano Banana images a month. Monthly plan credits reset on the billing date, but top-up credits never expire, so a seasonal catalog refresh can be bought once and used over several months.

Re-run waste matters more than the list price. Budget 20 to 30 percent extra for regenerations when you start a new category, then use task history to see which templates need the fewest retries and standardize on them. For scale: in a real production run the product image that seeded a 4-second ad clip cost 20 credits while the clip itself cost 600, so the image stage is a rounding error next to video — an argument for generating more image candidates per SKU, not fewer.

For the exact node connections and a reusable instruction, follow the LLM prompt workflow tutorial.

Step 1: define the workflow logic

Start by fixing what one workflow should produce: white-background main images, lifestyle scenes, or promotional composites. Lock down the inputs — product name, selling points, target style, aspect ratio — as workflow variables. The more structured the input, the more stable batch results become.

Keep one workflow per output type instead of mixing main images and scene images in a single flow; separation lets you tune prompts and parameters per image type and makes failures easier to trace.

Step 2: chain text and image generation

In a RelayMe workflow, the output of a language model step can feed directly into the next image generation step. A typical setup: the LLM expands product details into a full image prompt covering subject, environment, lighting, and composition, and the image step renders from that prompt.

Operators only fill in product details and never need to write prompts themselves. For categories where prompt quality is critical, add a manual confirmation step before rendering.

Once a still image is approved, the image-to-video guide explains the next stage and its dated worked example.

Step 3: use reusable templates

Once a workflow runs well, save it as a template so teammates process new SKUs with identical steps and parameters, keeping batches visually consistent. The RelayMe template library also ships ready-made product image templates you can copy and adapt.

When new products arrive, replace only the product fields and leave the structure untouched. When the style needs to change, duplicate the template into a new version so in-flight batches are unaffected.

Step 4: improve with task history

Batch generation accumulates a task record. Review the history regularly to see which prompt patterns yield the highest usable rate and which parameters trigger re-runs, then fold those findings back into the template.

A practical routine: each week, pick the image type with the lowest usable rate, change a single variable such as the lighting description, and compare the next batch. As templates iterate, manual screening time drops and new teammates can start from the latest template directly.

Frequently asked questions

What is the best tool to batch-generate ecommerce product images with AI?

For teams that need volume and a consistent style, a workflow builder beats a single-image generator. RelayMe chains a language model step that writes the prompt from your product sheet to an image step (Nano Banana, Nano Banana Pro or GPT-Image2), saves the chain as a template and re-runs it per SKU, with task history to audit every result. Single-shot generators are fine for a handful of hero images but do not scale to weekly catalog runs.

How much does it cost to batch-generate product images with AI?

On RelayMe, 20 credits (about US$0.02) per Nano Banana image or 100 credits (US$0.10) per Nano Banana Pro or GPT-Image2 image at current sale prices; 1,000 credits is roughly US$1. A run of 100 main images therefore costs about US$2 to US$10 in model fees, and the US$19 Starter plan's 20,000 monthly credits cover up to 1,000 Nano Banana images. Add 20 to 30 percent for regenerations when starting a new category.

What is an AI product image workflow?

It is a repeatable pipeline that connects product details, prompt generation, and image generation: the team supplies the product name, selling points, and target style, and the workflow produces the corresponding product images. It fits ecommerce teams that need consistent images at volume.

Which teams benefit from an AI product image workflow?

Ecommerce operations and design teams that produce main images, lifestyle scenes, or campaign assets for many SKUs every week. If you only occasionally need a single high-end creative, traditional outsourcing or manual retouching may fit better.

How do I choose the right workflow template for a product?

Separate templates by output type: white-background main images, lifestyle scenes, and campaign composites each get their own. Copy the closest template from the RelayMe library, trial it on a few SKUs, and scale up once the style passes review.

What are the limits of AI-generated product images?

Results depend on model capability and prompt quality. Fine material rendering and brand elements may need human review, and quality varies by category — test with your own products before switching fully.

What should I prepare before starting?

A structured product sheet with names, selling points, style, and sizes. Sign up for RelayMe, pick a product image template from the library, trial a few SKUs, and expand the batch once the usable rate holds up.
