Image Studio makes new pictures from a written prompt, or edits your own photos when you add them as references (pictures the AI copies from). You type what you want, pick a model, a size and a shape, and press **Generate** — the exact credit price shows on the button before you press it, and the result appears under **Latest**.

## Steps

1. Open **Image Studio** in the sidebar (page `/app/image`).
2. Type in the prompt box ("Describe the image you want to create..."). A counter shows how many characters you have used.
3. Optional — to edit or match a real product: press **Reference photos 0 of N** and upload JPG, PNG, WebP or HEIC photos. The number N is how many the chosen model accepts, up to 16. In your prompt, say what to change, for example "put this bottle on a marble table at sunset".
4. Press the model chip and pick a model. Use **Search models…** to find one by name. A dot shows its state: **Smooth** (running normally), **High volume** (busy, may take longer) or **Paused** (can't be picked right now).
5. Press **Model parameters** and choose **Size** (1K, 2K, 3K or 4K, depending on the model) and **Aspect ratio** (the shape, for example 1:1, 4:5 or 9:16).
6. If the model can make several at once, press the **1x** chip and choose up to 4 pictures per press.
7. Press **Generate · N credits**. The picture appears under **Latest**. Press **Download** on the tile, or open it full size.

## At a glance

| | |
|---|---|
| Credits | Shown on the **Generate · N credits** button; at the time of writing, 2 to 21 credits per picture depending on model and size |
| Max length | Prompt has no fixed cap; a warning appears past a model's own limit, and 100,000 characters is the hard ceiling |
| Sizes | 1K, 2K, 3K, 4K or Standard, depending on the model; shapes from 1:1 to 21:9 |
| Inputs | A prompt; up to 16 reference photos depending on the model (JPG, PNG, WebP, HEIC) |

| Best for | Product photos, ad pictures, picture edits, and starting frames for videos |

## Model families

Image Studio lists the models that are on sale right now; the list can change. The main families:

| Family | What the controls allow |
|---|---|
| GPT-Image 2 and GPT-Image 2.5 | GPT-Image-2 Standard takes up to 16 reference photos and goes up to 4K; GPT-Image 2.5 makes 1K pictures |
| Nano Banana, Nano Banana 2, Nano Banana Pro | Up to 14 reference photos; Nano Banana Pro goes up to 4K |
| Seedream 4.0, 4.5, 5.0 | Up to 10 reference photos; the failure tip names Seedream for realistic people and faces |
| Flux Kontext, Flux 2.0 | Flux Kontext takes 1 reference photo — good for editing a single picture with a prompt |

## Use when / Avoid when

| Use when | Avoid when |
|---|---|
| You want one picture made exactly from your own prompt | You want a full set of ready-made ads with words laid out — use [Image Ads](https://reviral.ai/docs/image-ads) |
| You want to change a photo you already have | You want a video — use [UGC Ads](https://reviral.ai/docs/ugc-ads) or [Create](https://reviral.ai/docs/create-video) |

## Example

Upload a photo of your perfume bottle under **Reference photos**. Pick a Nano Banana Pro model, set **Size** to 2K and **Aspect ratio** to 4:5, and write: "Image 1 on a wet black stone, soft morning light, water drops, product photo." Press **Generate**. To reuse a demo instead, scroll to **Start from an example** and press **Recreate** — it fills the prompt and model for you.

## Troubleshooting

| Message on screen | What to do |
|---|---|
| "This image model declined this request (its content rules are strict about realistic people). Your credits have been returned. Tip: try the Seedream model for realistic people and faces." | Switch to a Seedream model and press **Generate** again. |
| "This model is temporarily unavailable — please try a different model." | Pick another model. |
| "N of M images failed — your credits were returned. Try again." | Press **Generate** again. |
| "Image generation failed. Your credits have been returned." | Try again, or change the prompt or model. |
| "Reference photos trimmed to N for [model]." | The new model takes fewer photos; the extra ones were removed. |
| "Price unavailable, try again in a moment" | Wait a moment and press the retry button next to it. |
| "Image Studio is temporarily unavailable." | The page is paused; try again later. |

Saved pictures also appear in **Images** (page `/app/images`). They are kept for 30 days, then can be deleted — download what you want to keep. On the free plan (if you have never paid), downloads carry the REVIRAL.AI logo; see [the free-plan logo](https://reviral.ai/docs/free-plan-logo).

## FAQ

### How much does one picture cost?

It depends on the model and size. The Generate button shows the exact credits for your choice before you press it.

### Can I edit my own photo?

Yes. Add it under Reference photos, then describe the change in the prompt, for example put this bottle on a marble table.

### What happens if a picture fails?

The failure banner says why, and your credits are returned. If the model refused a realistic person, the message suggests trying the Seedream model.

### How long are my pictures kept?

Saved pictures are kept for 30 days, then can be deleted. Download anything you want to keep.

### Can I turn a drawing or sketch into a picture?

Yes, with the three GPT-Image-2.5 models: GPT-Image-2.5, GPT-Image-2.5 Flare and GPT-Image-2.5 Sunburst. Other models do not show the sketch pad. Press 'Draw a sketch', draw with the pen (6 colours, eraser and undo), then press 'Use this sketch'. Your sketch becomes a reference photo. If the prompt box is empty, a ready-made prompt is filled in that keeps your layout and adds nothing new. In our test, Flare followed the sketch most faithfully, and the plain model was faster.

### Can I change one thing in a picture I already made?

Yes, on pictures made with the GPT-Image-2.5 models. Press 'Edit this picture' on the result card. The picture is added as a reference photo, and you type only what should change, for example 'change the cup to blue and keep the rest the same'. Press 'Finish / HD' to send it to GPT-Image-2.5 Sunburst for a sharper final version. The Generate button shows the exact credits before you press it.
