Here are some common issues that occur when uploading or sharing photos on SkyDrive:
If the pictures hub is not displaying your entire set of SkyDrive picture folders it may be due to how the folder is configured on SkyDrive. The pictures hub only shows "Photo" folders. To change the folder type:
Click the folder that is not displaying photos and from the right pane, expand Information.
Under Folder type, click Change.
Select Photos and then click Save.
You may notice a "Mobile uploads" and/or a "SkyDrive camera roll" folder in your Pictures hub. These are normal, depending on how you use your phone:
Mobile uploads: When you manually choose to share on SkyDrive, pictures are stored in this folder.
Skydrive Camera roll: These are where pictures are stored after you enable the Automatically upload to SkyDrive setting on the phone.
Pictures uploaded automatically or manually via the "share with Skydrive" menu are at low resolution. You can upload your pictures at full resolution using the SkyDrive app, which is available in
Marketplace.
You are unable to delete SkyDrive photos from the Pictures hub. You can manage your SkyDrive photos using the SkyDrive app, which is available in
Marketplace.
If the battery power is low, pictures will not automatically upload to SkyDrive. If this happens, your phone might be able to upload the pictures, later, when you can connect the phone to the charger and have a data connection.
If you still have trouble uploading or sharing pictures, try resetting the phone.
