Existing image over csv import wont work

dear support,
my problem: i want to use existing images from their folders for the import (because i switch from toolset to geodirectory).
for example: an image exists in

/wp-content/uploads/2010/5/xxx.jpg

if i write the full url of this image in my csv field for “post_images” f.e.:

https://mysite.com/wp-content/uploads/2010/5/xxx.jpg

nothing happens in table

wp_geodir_attachments.

and
in

 wp_geodir_gd_place_detail

featured_image is NULL
after the import.

i´ve tried several settings to import the images for listings but nothing works. Like that format from the exported csv and so on.
https://mysite.com/wp-content/uploads/2008/03/966.jpg::https://mysite.com/wp-content/uploads/2008/03/242.jpg with ||| and without the |||

PS: I get no error and use the “Disable Real MIME Check” plugin.

any hints?

kind regards
