Only pictures that meet the requirements for uploading can be uploaded. If your image meets the requirements but still hasn't been uploaded, please check it as follows:
1. Image file name: Make sure the file format is JPG or PNG.
2. Web browser: Check if your web browser is updated, if not. You can also try uploading images by different browsers. The most compatible browser is Chrome, Firefox, and Safari.
3. Network connection: The network connection may be unstable when uploading. Try to re-upload using a faster and more stable network.
4. Corrupt file: If the file is corrupt, try to save a copy of it before re-uploading.
5. Insufficient cloud storage: Check your cloud storage is enough to upload more images.
