I have a Samsung Galaxy S4 mini. I cannot email more than 1 photo at a time

When I select 2 or more photos to email the email with photos attached sits in the outbox forever. The screen shows a faint"sending" but nothing happens. I have tried selecting the email in the outbox and the message comes up asking if I want to try sending again -sill no success.
Is their any way to overcome this and allow me to send several photos as attachments on an email?

It should send as many attachments as you add - up to a total size of 25MB. Most email providers won't accept emails larger than that.
