EMail on note 2/Android

Hey guys, i use the stock mail app, and i honestly really enjoy it on the note 2. I've had the same email address for many years and i just have loads of contacts for business i couldn't move it over to gmail. Problem i'm having is when someone sends me photos if they really sent me 6 only 3 will come in. If i check it on my iphone the correct amount of photos come in. Anyone know why that would be? I have the size set to 100KB. This is kind of a problem for me for i rely on the pictures that come through in email. Any help would be appreciated! Thanks.
