You’ll need to make sure you’re uploading JPG, GIF, or PNG images.
The best thing you can do to eliminate image upload problems is to resize your images. Your phone’s high-resolution images can be fairly large in size and while our site will accept them, the uploading and processing may take more time than your browser will allow, resulting in timeouts.
Unfortunately, the iOS Photos app does not support resizing photos so to do this you will either need to move them to your computer in some way, or use a third-party photo editing app.
Apple’s HEIC image format cannot be used on the web, as only Safari currently supports it.
