First make sure you have “Create ALT tags for images and buttons” selected in the options when you go to publish.
If that doesn’t do it or you need to change whatever Inspire creates you can do so fairly easily using jQuery (.attr or .prop). If you need instructions for this I will write them up but check the above first.
