EPUB Export with JPG images causes a validation error for the cover image due to an **already identified** InDesign bug
When you Export an EPUB with JPG images, it always causes a file type validation error for the cover image.
I have already identified the bug in InDesign. Instead of turning the cover art into an actual .jpg format, InDesign instead just rasterizes the first page of the book as a .png and changes the extension name of a .png file to .jpg without actually being the correct file format.
Please fix this.
