Custom Formatters

Try the Custom Formatters module to create a custom formatter, Tokens may help. There are some examples for inspiration: Custom Formatter Examples. 

Or implement through your own custom solution in a module or a theme: Create a custom field formatter.

Views Block

Another way of doing it is hiding the Image field on Manage Display, and creating a Views Block instead with a contextual node ID filter that outputs that image field along with the title. If you don't see the title available as a field in content views out of the box you can add a Relationship to that field to get it.
