Do you want that as additional value for the "Always show images" setting? Or are you asking for a setting to automatically download image attachments when on WiFi?

[weiserma]

My suggestion is for an extra value in "Always show images" but a new option "Auto download only via wifi" could work as well.

I'd like to work on it :)

I just found this issue before suggesting the same.

Actually this could be extended a bit more:

• additional option to automatically download images while on wifi
• additional options to select message size download limit while on wifi.

Basically we are not that concerned about message size nor downloading additional images while on wifi while using mobile data we are usually more interested in header and some lead into message.

Perhaps the option should be metered vs unmetered connection.

"on wifi" is generally understood as "unmetered" by users. android has logic for detecting metered wifi connections (typically hotspots from other phones), that can be used internally.

This is an old, old feature request, but I'd like to toss my support in. I may also suggest an additional setting:

• Download from Trusted Senders

This is separate from your contacts-- purely an internal list unique to K9 that whitelists specified senders and automatically downloads from them. See Aquamail's functional workflow:

1. Recieve mail, no images downloaded
2. Tap button/bar to download images
3. Button/bar becomes "remember for this sender"
4. Tap that button
5. In the future, images will download from that sender automatically

This would probably mean that "downloaded images on wi-fi" would become its own separate setting checkbox, that is then refined with the options:

• Always download all images
• Download from contacts
• Download from trusted senders
• Never download

The default behavior for mobile image downloading could also be split into its own checkbox, with the same options as above.

I realize I'm rambling. Does that make sense?

Edit to add: here's a markdown mock-up of what I mean:

• [ ] Download images on wi-fi
• Always download
• Download from trusted senders and contacts
• Download from contacts only
• [ ] Download images on mobile
• Always download
• Download from trusted senders and contacts
• Download from contacts only

K-9 Mail is a wonderful app, and that's why I was a bit surprised that it still doesn't offer the option to download images only when connected to Wi-Fi.

Since K-9 Mail is a mobile app, I believe it would be beneficial to have an option to automatically download images only when connected to Wi-Fi.

This feature would help maintain convenience when connected to Wi-Fi while also conserving data usage on metered networks and being useful in cases of very slow network connections.
