Blog Picture Issue

Hello everyone,
I have a problem with the new Oblivion Website I’m currently creating. For some reason my pictures on the “My Portfolio” and the “News Block “Blog Style”” won’t show pictures. All it shows is this:
My Portfolio Image Error: http://prntscr.com/74yc6r
News Block “Blog Style” Error: http://prntscr.com/74ycb6

You may think the image is to big, but that is not the case because it shows the image just fine when you open up the full blog or portfolio.

Examples:
My Portfolio Image full portfolio: http://prntscr.com/74yd77
News Block “Blog Style” full blog: http://prntscr.com/74ycui

If you happen to know whats causing this I would appreciate it very much. Thank you for all the help!
