Working with images in Corona

Loading an Image :
syntax:
display.newImage( filename [, baseDirectory] [, left, top] )
example:

newImage = display.newImage( "image.png", 10, 20 ) myImage2 = display.newImage( "image.png" )

Image Autoscaling:
The default behavior of display.newImage() is to auto-scale large images.To control manually we can use boolean value.
syntax:
display.newImage( [parentGroup,] filename [, baseDirectory] [, x, y] [,isFullResolution] )
example:

newImage = display.newImage( "image.png", 10, 20, true )

Images with Dynamic Resolution :
syntax:
display.newImageRect( [parentGroup,] filename [, baseDirectory] w,h )
example:

newImage = display.newImageRect( "Image.png", 100, 100 )
