If the images downloaded from the internet or any messaging app are not opening on an iPhone, try to re-download it and open it again. If the download process was interrupted earlier, there are chances that your JPG files got corrupted. An iPhone will not open corrupted JPG files without repair.

Open the JPG files in another image viewer app

If your Photos app does not open the JPG files, try to open it on another image viewer app. You can use Fast Image Viewer, Photo Viewer X, Phiewer (lite) - Image Viewer, and other image viewer apps to open the JPG files on your iPhone.
