Those tool tips are the title of the image and are a part of the image tag that is automatically generated by the featured image function.
If you wanted to replace or hide these tooltips you would have to use JavaScript, you could try a jQuery plugin like qTip.

much to change? can you tell what should be changed to remove the tips.
This can’t be easily changed in the code before it is output. The slide images are added as post thumbnails using the the_post_thumbnail function which automatically adds alt and title tags.
This is standard practice for all images using HTML, it would be best to remove or hide them using JavaScript so that they are still accessible to users who need them.
