Hi,. I'm having the same problem as well. I use Picasa Web Albums for my blog and upload photos to it via a third party programme (MarsEdit).

Just noticed today that all the images are suddenly of poor quality compared to previously.. PLEASE HELPPP
 
HI THERE I have figured it out.. if you have Google+ you need to go into SETTINGS and towards the bottom of the page there should be a PHOTOS section.

You need to TURN OFF 'Auto Enhance' and 'Auto Awesome'

This solved the problem for me..
