Image Limit in a Page

Just a quick question, why is it that WordPress is limiting the images that can be shown on one page? How do you fix the problem because I can only show a maximum of 14 images and whenever I entered the 15th image, the page returns me a blank page. My images are only around 44-56 KB in maximum size and the current page is only showing a thumbnail version of it so it shouldn’t be in the image size.

Thanks for your help!
