**Guided edit** changes one part of an image. You mark the area, describe what should change there, and pick a model. FlashBoards keeps the pixels outside your selection as they were, and adds the result as a new image next to the original, connected to it. Your original is never changed.

> **Note: Signed in and paid.** Each **Generate** is a paid AI run, charged to your balance like any generation. The editor shows the estimated charge before you start. See [Billing](https://flashboards.yaroflasher.com/docs/generation/billing.md).

## Open the editor

Select a still image on one of your own boards, open its three-dot **More actions** menu and choose **Guided edit**. It isn't offered for GIFs or on shared boards; work on a [private copy](https://flashboards.yaroflasher.com/docs/sharing/shared-boards.md) instead.

The image can be a PNG, JPEG or WebP without transparency, up to 8192 pixels per side and 32 megapixels.

If no model can run for your account, the editor explains why under **Model** and **Generate** stays disabled. Use **Sign in** or **See plans** if offered. If it says **Guided edit isn’t available right now.**, try again later.

## Mark the area

### Step 1: Choose a selection tool

Use the **Brush**, **Lasso**, **Rectangle** or **Ellipse**. Switch between adding to and removing from the selection to refine it. The brush size has presets and a custom value.

### Step 2: Refine the edge

**Grow selection** and **Shrink selection** move the boundary by a few pixels. **Undo selection**, **Redo selection** and **Clear** work on the selection only.

### Step 3: Move around

Zoom in and out, **Fit** the image, or view **Actual pixels**. Expand the editor for more room, and hold **Space** (or use **Pan**) to move the image.

## Generate and compare

Describe what to change in the marked area in **Instruction**, choose the model (**GPT Image 2.5 Flare** or **GPT Image 2.5 Sunburst**, when available to your account) and its quality, then click **Generate**.

When a result is ready, compare it with the original **Side by side** or with a **Wipe** slider. **Generate another** makes a second version with the same settings; the editor keeps your last two successful results so you can switch between them. **Adjust edit** returns to the selection and instruction for that result, and **Edit this result** starts a new edit from it.

If the image's proportions don't suit the model, FlashBoards works on a resized, padded copy. Fine detail inside the selection can change, but the placed image keeps the original's size.

## Place the result

Click **Place on board**. The edited copy is added next to the original as a separate PNG, connected to it. Board **Undo** removes it like any other change.

Results you haven't placed stay in the editor only while the page is open. After a reload, the generation itself can still be found in [Generation history](https://flashboards.yaroflasher.com/docs/generation/history-and-errors.md), but the edited copy has to be made again. **Download RAW output** saves the model's own output, before FlashBoards blends it into your original.
