A mensagem completa é algo assim:
DISPLAY: downloadPicture TYPE: DOWNLOAD STATE: ERROR
PRIORITY: NORMAL FILES: 0 / 1 BYTES: 0 / 17873 (0%)
Unable to complete transfer.
ERROR FILE: https://www.planwallpaper.com/static/images/foggygoldengatebridge.jpg -> C:\Users\ouroborus\desktop\%pictureName%
ERROR CODE: 0x80200013 - The server does not support the necessary HTTP protocol. Background Intelligent Transfer Service (BITS) requires that the server support the Range protocol header.
ERROR CONTEXT: 0x00000005 - The error occurred while the remote file was being processed.
Está bem claro o que está acontecendo: bitsadmin
exige que o servidor suporte Range
headers e planwallpaper.com não tenha esse suporte.
