This is a common dilemma Mary. I have some ideas, but first, a couple of questions.
Why the intermediate step of mailing to the tablet?
Is the tablet Windows or Mac?
By "desktop" do you mean a laptop, a desktop model computer, or the "desktop" (aka 'home screen' or 'startup screen') of one of these computer types.
If it's a desk-type computer, is it Windows or Mac.
Do you have any image editing software?
Also, are you able to set the resolution of your camera before you take the picture? A lower-resolution picture would email quicker. The iPhone offers several downsizing options when emailing large images, does the Samsung have anything like that?
