How the IMAGE function works
IMAGE function takes a URL as input. The
URL parameter can come from existing URL fields in the data source, or the parameter can be an expression that builds URLs from other fields and functions.
Alternative Text parameter provides the the image's alt text, which can be used by screen readers to assist vision-impaired users.
To display images in a report, add the
Image field created by the
IMAGE function to a table in your report. The size of the image displayed depends on the width of the column containing the image. If the URL is incorrect, or the image type is not supported, a broken image icon is displayed instead.
The Type drop-down menu is disabled for

Limits of the IMAGE function

Image fields only work in tables. If you change the visualization type, any
Image fields in the chart will be ignored, or the image URL will appear as the dimension value.
Images and your data
In addition to the name of a file you want view, hyperlinks and image URLs can also send information, in the form of query parameters appended to the URL path. For example:
This URL is requesting the JPEG image
somefile.jpg. It is also sending data via the
When reports or data sources contain hyperlinks or image URLs, you should make sure that these point to trusted domains, and that any additional data being sent makes sense to you.
To help with this, images in Data Studio have the following limits:
Images and the data control
When a report includes a data control, images appear when:
- the data control is showing the default data set
- the data control is showing a different (non-default) data set AND the
Imagefield is serving images from a trusted domain. Currently, this includes most Google domains.
If the data control is showing a different (non-default) data set AND images are requested from an untrusted domain, images won't appear. Instead, the table will display the image URL. Report viewers can click the URL to view the image, and are shown a dialog asking them to make sure the link goes to a trusted domain.
Images in copied data sources
When you copy a data source, all
Image fields are disabled in the copy. You can re-enable images by doing the following:
- Edit the data source
- For each field you want to enable, click
- Select Enable.
