try removing the
style="width:50%" piece
You have how many with this?
(which really should be in the CSS so you could fudge the amount from 0 to 100%)
BTW IMHO the
alt= should be a text description of the images content, not the file name What the
is a 'e9781447582991_fig002'
Alt is used by text to speech it might as well be "" for all the use it provided
