Notice: Undefined property: stdClass after upgrade from Drupal 7.8 to 7.10

I just upgraded from Drupal 7.8 to 7.10. All seemed to go pretty well, except that now for the pages with any custom image fields that I have created, I am getting these 2 errors at the top of the page(s):

Notice: Undefined property: stdClass::$field_imageurl_staff_width in field_sql_storage_field_storage_load() (line 360 of /home3/covellog/public_html/modules/field/modules/field_sql_storage/field_sql_storage.module).

and

Notice: Undefined property: stdClass::$field_imageurl_staff_height in field_sql_storage_field_storage_load() (line 360 of /home3/covellog/public_html/modules/field/modules/field_sql_storage/field_sql_storage.module).

where $field_imageurl_staff is my custom image field.

i tried turning off error reporting in my php.ini file. but this is not working.

please help.
thank you
Jean (drupal newbie)

p.s.
i now see my problem goes much deeper. i just tried to upload a new staff image to a staff page and i get this error. (see error message below)

this all was working fine in v7.8 before the upgrade to 7.10.
any ideas?

thanks, jean
