This article explains how to set a default value for Image fields on a new form.

There isn't any OOTB way of setting a default value for the Image type field on a form. The default value in the field dictionary's doesn't set the default image for the record. However, a Before insert  Business Rule can be written to populate the field. 

The images are stored in the sys_attachment table. In the sys_attachment table, the "File name" is the name of the field, and "Table name" is ZZ_YY plus the name of the table (e.g., ZZ_YYincident). "Table sys ID" is the sys_id of the original record.

You need to create a before query Business Rule using the following API method:

GlideSysAttachment.copy(String sourceTable, String sourceID, String targetTable, String targetID)

Copies attachments from the source record to the target record.

Example:

If you want to populate the image field on a new Incident form, use the following format.

GlideSysAttachment.copy("ZZ_YYincident", "<Table sys ID>", "ZZ_YYincident", current.sys_id);

Procedure

---

1. If there is already an image added on an existing record (e.g., Incident), ignore step 2
2. Add an image to the image field on the form
3. Go to sys_attachment.LIST
4. Find the recent record for the field (record of the image that you want to use as a default)
5. Copy the sys ID from "Table sys ID" column
6. Create a Before Insert Business Rule on the Table as follows:
   
   When: before - Insert
   Active : <checked>
   Advanced: <checked>
   **script:
   GlideSysAttachment.copy("ZZ_YYincident", "<Table sys ID>", "ZZ_YYincident", current.sys_id);
   
   
7. Result: Image field will be auto-populated when a new record is created in the table.
   
   Note: The steps provided above are for Incident table. You can use the steps for other tables as well.
