Overlapping text

Hello everyone,
I recently updated the lightbox gallery, and I had my gallery the way I wanted it. However, I am having trouble with the text overlapping with each other. I know there is a way to fix it by adding a script, but I am not familiar with this process. Any suggestions regarding this issue? Any help would be wonderful!
