Are the image tags completely missing or are the contents of the title attributes missing? Or something else completely?
If you switch to HTML view in the editor on a post which is supposed to have an image what does the HTML img tag look like if it’s there? What exactly is wrong about it, some examples of before and after import.
Other tags are correct. Everything else looks good. Here are the examples.

After some debugging I found the solution. In wp-includes/kses.php I allowed title as attribute on image tag. Now the title tag doesn’t disappear after import.
'img' => array(
'alt' => array (),
'align' => array (),
'border' => array (),
'class' => array (),
'height' => array (),
'hspace' => array (),
'longdesc' => array (),
'vspace' => array (),
'src' => array (),
'style' => array (),
'title' => array (),
'width' => array ()),
