Flickr upload does not work on Drupal 6

I tried using the latest development version of the Flickr upload module for Drupal 6, but without any succes.

First of all the module description indicates that it requires the flickr module, however it actually needs the FlickrAPI module.

The module gives an error when I try to upload some images. I get the following messages in return:

* warning: Illegal offset type in isset or empty in /home/namehere/domains/namehere.nl/public_html/includes/file.inc on line 525.
* warning: Illegal offset type in /home/namehere/domains/namehere.nl/public_html/includes/file.inc on line 530.
* Failed to upload the image file; the flickr directory doesn't exist or is not writable.
