# Thumbnail
Use thumbnails as a visual anchor and identifier for an object. They should be used along with text to provide context.
## Best practices
Thumbnails should:
- Be one of 3 sizes:
- Small (40 × 40 px): Use when the medium size is too large for the layout, or when the thumbnail has less importance
- Medium (60 × 60 px): Use as the default size
- Large (80 × 80 px): Use when an thumbnail is a major focal point. Avoid this size in lists of like items.
## Content guidelines
Any time you use an image to communicate a concept on Shopify, it’s important to use descriptive [alt text](/content/alternative-text). Doing this is important for [accessibility](/guides/accessibility) because it allows screen readers to describe what’s in the image to people who may not be able to see it.
For thumbnails, we recommend using a format that describes what will show in the image:
- `alt="Photo of {product}"`, e.g. "Photo of black t-shirt with cartoon tiger"
- An empty `alt=""` attribute ignores the image in assistive technologies such as screen readers, and may be used on decorative thumbnails
## Examples
### Default thumbnail
Use as the default size (medium).
```jsx
<Thumbnail
source="https://burst.shopifycdn.com/photos/black-leather-choker-necklace_373x@2x.jpg"
alt="Black choker necklace"
/>
```
### Small thumbnail
Use when the default size is too large for the layout, or when the thumbnail has less importance.
```jsx
<Thumbnail
source="https://burst.shopifycdn.com/photos/black-leather-choker-necklace_373x@2x.jpg"
size="small"
alt="Black choker necklace"
/>
```
### Large thumbnail
Use when a thumbnail is a major focal point. Avoid this size in lists of like items.
```jsx
<Thumbnail
source="https://burst.shopifycdn.com/photos/black-leather-choker-necklace_373x@2x.jpg"
size="large"
alt="Black choker necklace"
/>
```
