Need help big time

Hello all. Im having a major issue with my website.

My site is seasonal. I have been posting stories on my site with pictures. http://www.TeamGridiron.com

For whatever reason, when I try to post pictures that I just took today on my first article of the season, I am getting this notice Fatal error: Out of memory (allocated 66846720) (tried to allocate 13824 bytes) in /home/teamgrid/public_html/wp-includes/media.php on line 253

I cant figure it out. Ive posted pictures that I previously had on the site and they worked. Ive used the same exact camera, with no different configuration. Anyone that could help please do!!!
