# Tutorial thumbnail OG image template

How-to video thumbnail: a screenshot in a tilted app window with a marker circle and a curved arrow on the spot that matters, the tool's logo on a big tile and a bold promise next to it.

- Slug: `thumbnail-tutorial`
- Preview (real render): https://shareglint.com/storage/template-previews/thumbnail-tutorial.jpg

For tutorial channels, SaaS academies and course creators. The circle sits where `highlight` says and dims the rest of the screen; the title autofits under a marker underline. Without a screenshot the window shows a sketch of an app, and without a logo the tile shows the tool's initial. Wide frames put the title on the left and the window on the right; square and vertical frames put the window on top.

## Fields

Every field is optional. Long text shrinks to fit instead of overflowing; an image field takes a public URL that we fetch on our side.

| Field | Type | Description | Example |
|---|---|---|---|
| `title` | text | What the video teaches, in a few words. (default: How to do it) | Build a live dashboard in 10 minutes |
| `tool_name` | text | Name of the tool, shown under its tile. | Northwind |
| `step_label` | text | Label in the accent pill, e.g. Part 1 or Lesson 3. | Part 1 |
| `level` | text | Difficulty: beginner, intermediate or advanced (fills one, two or three bars). | beginner |
| `highlight` | text | Where the circle goes on the screenshot: top-left, top-right, center, bottom-left or bottom-right. (default: top-right) | top-right |
| `channel` | text | Channel or school name at the bottom. | Northwind Academy |
| `tool_logo` | image URL | Logo of the tool, shown on the big tile. | https://example.com/images/logo-northwind.png |
| `screenshot` | image URL | Screenshot of the app or the result. | https://example.com/images/dashboard.png |
| `accent` | colour | Brand colour as hex, e.g. #6366f1. Drives buttons, highlights and the background glow. (default: #e11d48) | #e11d48 |
| `theme` | dark | light | Colour scheme: dark or light. (default: light) | — |

## Make it yours

accent and theme change per request. For anything more, copy the template into your account: you get an ordinary HTML template with the same fields that you can edit in the dashboard or through the API. If the slug is free on your account, the copy takes it — your integrations switch to your version without changing a line.

```bash
curl -X POST "https://shareglint.com/v1/templates/library/thumbnail-tutorial/copy" -H "Authorization: Bearer sk_live_YOUR_KEY"
```
