Viewing photos with caption on mobile devices

Hi, I have multiple photos with captions. The pictures with captions does not show up properly on mobile devices. The pictures usually doesn't appear and the caption letters are viewing vertically without the pictures. I usually have to refresh the page on my mobile device about 4 to 5 times before the pictures load properly. Here's a sample page on our website with multiple photos with captions http://www.aedunlv.org/members/executive-board-officers. Is there a fix for this to make sure that the pictures with caption opens up properly without having to refresh the page multiple times on mobile devices. I tried this on both iPhone and Samsung as well and it doesn't work. Thank you.
