Images are not displayed in Cp7/SCORM/HTML5

Hello, everyone.

I am a Japanese Captivate7 user.

Captivate7 is a good authering tool for us.

I am belonging to some projects and using this tool.

In project-A, we are making a SCORM1.2/HTML5 content incuding 150 pages, many images, many advanced actions, 10 quizzes but not including videos, sounds. In this content, some of images are not dislpayed on the specified slide (Quiz No.6 or 7), refer to Fig.1.

Note : no images in green line

In this time, HTML data between server and client is funny, PNG images are recognized as txt/html in server side. Normally, I think an image is recognized as image/html in server side.

Refer to Fig.2

This is issued in only Safari (IOS7,6 and Safari5.1.7).

Please help me ASAP.
