fixed remote upload of images (eg. the one in your backup Google folder)

if you try to upload an image from your Google backup for example (ie is not in your local storage) i'ts doing nothing.
After this fix it works: the changes for uploading image are made only in ChatActivity and Wallpaper one..
Are you using image upload elsewere?
