Adjust mobile functionality/view of photo gallery (Wordpress plugin)

I am using the free version of the "Photo Gallery" Wordpress Plugin. More details here... [login to view URL] I like how the site looks on the desktop version, but on my iphone when you scroll over the gallery images it makes the lightbox appear causing a bad user experience. I would like to reduce the sensitivity of the gallery when the user is scrolling or even disable the lightbox for mobile altogether. I have $10 to spend on this project and would like it finished by this afternoon (EST) if possible. Send me your quotes and I'll message you with the site link and details. Thanks!
