CSV import fields

I am trying to import our products using the Ready-CSV Products Importer and want to import a field called “Images” which contains the image file
and location /uploads/somefile.jpg What should I call the import field
so that it gets accepted by the database and shows in the Product
edit page ?

Also having trouble importing a field called “Parameter:[size_09]” which is the code( meta key) for size . Have I formatted it incorrectly ?

Many Thanks
