In the example below two images are imported using ee.Image().

// User specified parameters

// create vizualtion settings
var vizl5 = {min:0, max:0.3,bands:['B4', 'B3', 'B2']};
var vizl8 = {min:0, max:0.3,bands:['B5', 'B4', 'B3']};

// Data

var img1984 = ee.Image("LANDSAT/LT5_L1T_TOA_FMASK/LT51190381984217HAJ00");
var img2013 = ee.Image("LANDSAT/LC8_L1T_TOA/LC81190382013104LGN01");

// Add to map
Map.addLayer(img1984,vizl5,"1984 image");
Map.addLayer(img2013,vizl8,"2013 image");
