moodle fix required post migration

We have migrated a moodle site from one server to another. Since the migration we have upgraded from moodle 2.4 to 2.7. Since the migration content images are not showing. I think we have to a configuration problem - need someone to check and fix. If you know moodle and have migrated between servers i am sure this problem will take you a couple of mins to fix. Should be quick fix for moodle expert - budget = 20$
