I can't import images I'm using the Feeds and Feeds XML XPath Parser modules on Drupal 7.
While there is no problem importing all other fields (Title, body, etc.), it does not populate the image field in my nodes.

Feeds debug mode shows all paths to be relative, so I'm using Feeds Tamper to rewrite the relative paths to absolute paths (all on the same domain). Still, no images are being saved. 

There are no errors displayed on the import page, nor in Drupal logs.

UPDATE: After some more altering the image paths via Feeds Tamper, now the following error is shown in the logs:
    Invalid enclosure ""

Where should I start debugging this?

Thanks!
I had a similar issue while using Feeds, Feeds XLS and Feeds Tamper. I solved it by copying the images in the path mentioned before importing using Feeds.

I am not sure but I think you should first run a script that copies the images onto the path mentioned in the Image field and then import nodes using Feeds.

For example, if your path to images is 'sites/default/files/myimages', you should first copy the images to 'myimages' folder and then run Feeds because Feeds/Feeds Tamper simply populate the file path AFAIK. These modules do not actually save the images.

Let me know if this helps.
