Images

Images within emails are shown as blue squares
with a question mark. Is there a setting that would
show images in full.

[Kostya Vasilyev]

This is the new function which prevents spammers from tracking you and validating your email via linked images.

It's on by default, like in stock Email app.

Unlike stock Email app, you can turn it off.

Tap the "settings" icon on the right side of the "Show images" bar, then turn off "Show only from known" in the settings screen that shows. The change will apply from the next message on.
