image path for wp_generate_attachment_metadata

Hey all,

For wp_generate_attachment_metadata and wp_insert_attachment, what does the file path have to be? Absolute? Relative to the WP install root? Relative to get_option('upload_path')?

I’ve tried all three options, but none of them seem to work. A post of type ‘attachment’ is inserted into my database, but when i coupled all three attempts with wp_update_attachment_metadata, the actual information regarding the image file isn’t inserted into wp_postmeta.

Thanks!
