Storyline 360 Publishing to HTML5 Blurry Images

Hi, I am still noticing blurry images when publishing my courses in Storyline 360 to HTML5. I have tried to set publish quality options to custom optimization at 100% for images and the images are still blurry. The only way I am able to get the images to not look blurry is to replace all the image files once the course is published, which other users have also talked about. This is not ideal because you have to rename all of the original images to match what Storyline renames the images to when published. Is there a better way to make sure images have the best quality as possible? It would be great if there was an option to not have images compressed at all when publishing. We have clients who are not happy with the quality of our images since they always look blurry.
