I got this solution online from your articles:
To solve this issue, Please select converted JPEG image instead of PNG where image is missing , Or you can re upload PNG . If you want to keep "Convert PNG to JPEG (lossy)" option on, make sure that "Make a copy of my original images " option is also on. So the image missing occurrence will not happen again. Or You can use image after converting from PNG to JPEG.
My issues is that, we have Hundreds of blog entries and going through wach post 1 by 1 and re-uploading the image or converting the path is NOT something we can afford to accomplish.
Please tell me what solution can bring back all of our .png images that we converted to .jpegs?
