# system.kanoa.cmms.getImageThumbnail(chkImageId)

Retrieves a resized, lower-resolution thumbnail version of the image associated with the given `chkImageId`. 
This is intended for display contexts like list views, galleries, or table cells where loading the full-resolution image (via `getImage`) would be unnecessarily slow or heavy � 
the thumbnail is generated and stored ahead of time by `processImage` when the image is first uploaded.

### Parameters
**chkImageId** `Integer`: Id of image to retrieve<br />

---
### Returns
**image** `byteArray`<br />

---
### Example
```python
chkImageId = 42
thumbnailBytes = system.kanoa.cmms.getImageThumbnail(chkImageId)
```
