You cannot upload a picture on your iPad. The only way to add pictures is by sending them to the iPad from a blue tooth enabled device. If this is not possible, have the other person 7upload the picture to iCloud and you can get it from there.
1.Connect your iPod, iPhone, or iPad to your computer and select your device. 2.Click the Photos button. 3.Select “Sync photos from” and choose an album or folder from the pop-up menu. (If you’re using Adobe Photoshop Album or Adobe Photoshop Elements, you can export photos directly from those applications to your device by choosing Photoshop Album or Photoshop Elements from the pop-up menu.) 4.Choose whether to move all your folders or albums, or only selected folders or albums. 5.To also move the full-resolution versions of these photos to your iPod, select “Include full-resolution photos.” 6.Click Apply.
