How can I give my users an option to display their user profile pictures or an avatar

Add a custom profile field ...a checkbox preferably. When users check it then the profile pic will be displayed instead of the avatar.
Then in your postbit use something like this
<if condition="$post[fieldX]"
display profile pic
<else />
display avatar
</if>
you can find the code for both avatar/profile pic form the templates.
