[Plugin: NextGEN Gallery] No image title showing on my slimbox window

I am using NextGen gallery with slimbox but my titles are not visible in the slimbox image window. When I look at the HTML generated on the gallery page (attached an example of one image below) I see that the img tag has a title attribute (which is correct from the gallery) but the a tag has a blank title attribute and that is the one the slimbox code is using to to generate the image display.

What I really want is to control what image meta data will be used in the slimbox window. In my case I want the file name to appear there. To get that NextGen would need to fill the a tag’s title attribute with the file name.

Would it be possible for a future version of NextGen Gallery to allow control over what information appears in the slim box window?
