1. The mobile phone failed to upload, because the uploading rule of Tencent QQ space is that there is a certain uploading limit every day. If the limit is exceeded, the upload will fail.

2. Network problems. When the network conditions are not good, sometimes the uploaded photos will not be displayed. If this is the case, uploading on a different computer or at other times may appear.

3. This kind of situation generally does not appear, but it was uploaded and deleted for some reason. Generally, illegal pictures will be deleted by the system after uploading.

4. The format is wrong. At present, QQ photo album only supports pictures in jpg, gif, jpeg, png and bmp formats. Gif format photos cannot be rotated and added with spatial address. Please look at your picture format. If it is not in these formats, it can only be uploaded after conversion.

It is generally slow for mobile phones to upload photos directly to space, which leads to overtime service and upload failure. This is related to the size of your photo, the speed of your mobile phone, and the stability of mobile phone networking. But sometimes the network connection number can be uploaded successfully, and some have to try several times.

There is also a data cable connecting the mobile phone and the computer, which is faster. You can also take the photos to the computer before uploading them, which will be faster without going through the USB interface.
