Seems like the module is not capable of finding the imagefiles. I tried the standard field_image and a custom image field - none worked.
Tried it on two diferent instalation of D7
(yes I patch out the dependency on upload).
Errorcode:
Notice: Undefined index: sv i _inline_fileobj() (rad 307 av ..sites/all/modules/inline/inline.module).
Warning: Invalid argument supplied for foreach() i _inline_fileobj() (rad 307 av ..sites/all/modules/inline/inline.module).

Where image should be, in red: NOT FOUND: filename.jpg

william haller commentedI found this also, but only when I had the structure -> content types -> basic page -> manage fields -> Widget set to media file selector. With it set to image, it at least puts the image on the page inline without warnings. Now if it wouldn't display it below the page as well, and flowed the text around the image, all would be well, but you might try that setting and see if it helps you move closer.
