Download images only when on wifi

[mbrethes]

Hello there,

For those unfortunate people who have a limited mobile data plan (mine is limited to 50Mb/month), it would be useful to have an option that would allow not to download multimedia content (such as images) when the smartphone is on "data (3G/4G)" mode. The download could be then either manual (by touching the message that shows an "image" icon) or automatic when the phone gets connected to wifi...

Many thanks in advance,
