I just upgraded my software on my S4 & discovered that the option to select my photo size for emailing had disappeared.
I was able to get it back by going into my email settings.
Click on the EMAIL icon
Click on the bottom left menu key & select SETTINGS
Click on Composing & sending
Click on Default image size
You will then see the list of options....
Original
Large (70%)
Medium (30%)
Small (10%)
Always ask
Mine had changed to a green dot in Original.
I changed it to Always ask & i now get the option to reduce my photos when emailing them.
I hope this helps.
