Do you need to attach an image or photo to an Activity? The best way to do that is to attach it to an Activity Form. You can learn how to create an Activity Form here.
Step 1 - Open Activity Form
Go to Activity Forms in My Company settings, and click the Activity Form where you want to attach the photo.
In this example, we're going to use a Progress Report Form.
Step 2 - Add Question Field
Once the form is open, scroll down to the blue plus button to add a new field.
Add your photo field. You can ask a question like, "Would you like to add a photo?" or shorten it to "Add a photo?" In that case, you would put that question as the label in a Yes/No field. Click Add, then Save.
Next, click on the plus down arrow icon (see below) to add an optional field based on the answer to this question, like such:
Step 3 -Add File Upload Field
Add a File Upload field called "Add Image" or "Add Photo."
When the field editor opens, under "Visibility," check the box to only show this field if "Yes" is the value. Click Save, and you're done.
NOTE: For this form to appear within the Activity, it will need to be attached to that Activity. To attach this form to an Activity, check out this support article.
