Captivate exports my JPGs as PNGs

New Here ,
Jul 20, 2016 Jul 20, 2016

We are attempting to publish a Captivate project using the HTML publish option. Our client is very concerned about their bandwidth usage, because of the size of their target audience. Because of this, we are required to stay under a 1.5Mbps bandwidth.

We optimized our images, sound, etc, build a project (it's rather large, around 350 slides). However, when we export the final HTML package for LMS

All of our JPGs are converted to PNGs.

This is unfortunate, because our JPG images are roughly 50-80kb, but, once exported to PNG, they're over 300kb. This means we're downloading over four times as much data as is really necessary to view a given slide. Is there a way to get Captivate to publish to HTML and keep our images as JPGs?

There appear to be all kinds of publish settings for image quality, but none appear to actually affect image quality or compression. To make matters worse: this project is large at 350 slides, so publishing for testing purposes has already wasted many, many hours.

All suggestions appreciated!

Tommy
