When the browser comes across this attribute, it loads the LOWSEC image first and then when the entire page has been downloaded the LOWSRC image is replaced by the actual image.

Reducing the file size of an image file

File sizes can be reduced considerably if the pixel dimension of the image is not too large. This adjustment may not be possible in all cases. You should aim as far as possible to create pictures within 170(width) and 113 (height) pixels. There are chances of distortion of the image when the number of pixels is reduced therefore the images to be resized should be very carefully selected .You should avoid images to be resized should be very carefully selected. You should avoid images with thin lines, few details and photographs taken from a long distance. It is safer to consider images with bright color and a good clear quality for resizing.

Reducing the pixels in an image definitely in most cases reflects on the quality of the image but if they are done with care the quality loss can be minimum.
