For Salesforce Lightning, you must complete the following steps in Salesforce Classic and then merge the Classic Dashboard element in a Lightning button. Dashboard images merge in PPTX templates if the photoURL field is on the master object only.
You can include an image from a dashboard in a Conga Composer merge document by using an IMAGE: field.
IMAGE special merge fields are supported in Word and PPTX templates. (The instructions below are for Firefox, which is easier to use for accomplishing this task).
- Open the Dashboard. Right-click on the dashboard metric that you want to use. Select Copy Image Location.
- Create a long text area field in Salesforce in which to store this value.
- The value you copied in step 1 can now be pasted into this long text area field on a record.
- Use an IMAGE: merge field to grab the value of the URL.
