My cover images are not showing on my Kindle for PC when in "Library view". I found that if i add cover image to file that doesn't have cover image at all then the cover is shown in Library view. But if the mobi file has a cover image and i only try to change it it doesn't show the cover. So, if i want to make the cover visible i have to delete the old cover image and then add the new image but i can't find way to delete the old cover image.
Does anyone can help me with this?
