Images not fully uploading

I am having issues uploading images to my blog in the media upload. When I finish uploading no error message appears but there is a broken file image. then when I go to the blog post the tumb-nail works but when you go to the specific blog address the image doesn’t work. I know there is an issue in the image URL but how do I go about fixing it?

working image url: http://cameraclubny.org/ccny_blog/wp-content/uploads/2013/04/IMG_4183.jpg

what wordpress links it to: http://cameraclubny.org/ccny_blog/2013/04/01/2757/wp-content/uploads/2013/04/IMG_4183.jpg

my site is: http://cameraclubny.org/ccny_blog

and en example of a specific blogpost is: http://cameraclubny.org/ccny_blog/2013/04/01/2757/

thank you!
