.log files not logging which stimuli was used

Description of the problem:

Pavlovia failed to produce .csv files for many of the participants in my study. Therefore, I have resorted to analyzing the .log files. Unfortunately, it looks as though the .log files did not capture the image stimuli file name.

1169.7763000000716 EXP Routine1: image = {}

Is there something i am missing here? Are the image file (names) hidden somewhere? Thanks.
