从应用程序和电子邮件中检索保存的图像。

I am succesfully saving an image to my app after the user takes a picture. What I want to do later is, when the user comes back to the app I want them to be able to email the photo as an attachment. I am not having any luck getting the data from the app converted to an image so I can add as an attachment. Can someone point me in the right direction please. Here is where I save the image after they have taken a picture.I am succesfully saving an image to my app afte
