App works but needs some updates

What it does have seems to work. It would be better if the user would be able to enter the megapixel and dpi as an input and not a slider. Many cameras have larger megapixels then this app allows. It would be better to enter a dpi as the slider does not allow enough choices. The proportional calculator should auto calculate x and not need to press resize. It would also be helpful to have a choice to get a list of different size.
