When creating a EPUB with jpeg images there is always a .PNG file
When creating a EPUB with jpg images there is always a large .png file in the EPUB (it this is not an image). Publish Drive is refusing my EPUB because of this .PNG file.

It seems, you are selecting 'Rasterize' option under 'Cover' drop down in 'Export Options' dialog of EPUB.
InDesign exports a PNG for cover of EPUB. If you do not want a cover in your EPUB, you may select 'None' option under 'Cover' in 'Export Options' dialog of EPUB.
Please let me know if it solves the issue.
