Individual profile pages not responsive

[marcnjaramillo]

This is a minor fix. The profile image is not responsive on small screens. Since the profile image and it's parent div are using the max-width property, this should be set to 100% rather than a specific number. The max-width property of the profile image parent div also has a typo that needs to be fixed. However, the same applies to this property as well: it should be 100% rather than a specific number.
