# Exercise 3.3 (Challenge): Change image size

Remove the *Scale width 1200* effect in the *Job Posting Image* style and replace it with Scale and Crop, applying 1200px wide and 400px height dimensions.

Review how GovCMS updates the *Job posting* images for the existing content.

**What if you want to change the image size?**

The original image is saved as a backup and can be changed. If you decide to change the *Job Posting Image* style later (for example change the image’s dimensions to 200 x 200) GovCMS will automatically resize all *Job posting* images. You can also completely change the image style used in a content type by editing the content type display settings. This also flushes the cached versions and creates new, resized versions (which are copies of the original).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://salsa-digital.gitbook.io/govcms-site-builder/unit-3-manage-media/review-configuration-of-image-media-display/exercise-3-3-challenge-change-image-size.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
