Answer 1

Your path @"/Imagenes/30775.png" seems to be wrong. Double check it. Otherwise following should work

 UIImage * myImage = [UIImage imageWithContentsOfFile: dataPath];
_img.image = myImage

Answer 2

 NSString*ext= [NSString stringWithFormat:@"/Imagenes/30775.png"];

Your path is wrong.I guess the Imagenes is a group in your project. So xcode is not create a folder in your project main folder. The groups is only helps you to view the files easily in the xcode program. Also you don't need stringWithFormat .

Try this;

 NSString*ext= @"30775.png";
