General error: 1366 Incorrect integer value while uploading image
You don't have any values for these columns in the SQL query: field_third_section_image_alt, field_third_section_image_title, field_third_section_image_width,
field_third_section_image_height
So there must have something for these fields in order for the query to work. Have a look at the code and see why they are not set.
