Samsung Galaxy S4 — Email Images

Hi,

I'm new to the Samsung S4. Since the latest lollipop update I'm having problems with images in emails.

I must have a setting somewhere to only load images when I press "show images" and that's fine.

However, when I press show images, and close the e-mail, I then have to press show images again - it doesn't remember the image (or the fact I have already indicated I want to show images for that e-mail).

Actually the image sometimes disappears even if I don't close the e-mail.

I don't remember having to do that before. It happens on both wi-fi and 3g, and I don't have any restrictions on background data for the e-mail app. It's in the stock e-mail app (not the gmail app), but for emails in my gmail account). How can I make it keep the images in the e-mail at least until the e-mail is too old to be displayed?
