Remove Caption

Is there a way to disable the photo caption displaying under the file name in the galleries?  I am new to using Evoto editing software, and apparently when I export out of their program it is embedding "Evoto" in the metadata somewhere, and it is displaying on thousands of images that I have loaded to my site.  When I click on an image on the admin side, I can delete or change the title, caption, etc., individually but I need a bulk way to remove this without having to re-upload all of these images :)  Thanks! 

Go to Design -> Edit My Theme -> Additional CSS and add this code to the additional CSS section and save: 

.photocaption { display: none; } 

That worked, thank you so much!!!
