To set your profile photo, start by logging a photo (OR, you can opt to use a previously logged photo. All photos on your entries list can be set as your profile photo). Once the photo you wish to use is safely in your entries list, click on the entry title to view it as an individual entry. You will then see a sidebar on the right of the page with a list of Actions. Click on Set as profile photo and confirm. And voila! You'll have yourself a profile photo. Change your profile photo anytime by repeating these steps on another photo of your choice.
