Your images aren't displaying on your page now so I can't
see what you mean but another thing that will cause
distortions in images post upload is using the height and
width parameters of the img src tag to resize an image.
That's generally a no no. Squeeze a large image into a
small space and all sorts of distortions can show up even
if the image is resized proportionately.
Also make sure you're saving in the right format. Your page
has coding for gif images (that can't be found) that sound
like photos. Photos are better saved as jpg.
