D6 to D7 Having trouble in migrating the image feilds

I am having trouble in upgrading drupal 6 to drupal 7. we have a CCK image field and I am getting the following error..

Missing field module: 'image'. This field cannot be migrated.
Changed field type: The 'field_thumb_image' field type will be changed from 'filefield' to 'image'.
Missing widget: The 'image' widget is not available for the field_thumb_image field, it will be set to the default widget.
Missing formatter: The 'image' formatter used in 5 view modes for the field_thumb_image field is not available, these displays will be reset to the default formatter.
Missing formatter: The 'hidden' formatter used in 2 view modes for the field_thumb_image field is not available, these displays will be reset to the default formatter.
Missing widget: The 'image' widget is not available for the field_thumb_image field, it will be set to the default widget.
Missing formatter: The 'hidden' formatter used in 3 view modes for the field_thumb_image field is not available, these displays will be reset to the default formatter.
Missing formatter: The 'image' formatter used in 4 view modes for the field_thumb_image field is not available, these displays will be reset to the default formatter.

I have googled and went thru different drupal forums but did get the exact solution... if this is duplicate topics please guide me to the right topic.. though i have tired following modules and forum topics
