I've noticed that when you go to product page from the shopping cart clicking on the product, options as images doesn't selects properly. To fix this find code in catalogoptions_images.php

if ($iec=='1') { $checkedd=''; } else { $checkedd='checked'; }

and replace it with the code

if ($selected_attribute != $opti_array['id']) {
if ($iec=='1') { $checkedd=''; } else { $checkedd='checked'; }
} else {
$checkedd='checked';
}

Seems to me that's correct.
