Hello all.
I have a problem with the multiple images attached to the survey form. On other occasions the reports with multiple images have been produced without a problem, however, we have had some problems when the reports with a lot of images, giving a sending error without any other related information.

In some cases, the report cannot render the images giving an error when produced.

The images do not have a size restriction

What's could be the problem? Any idea?
