Images broken after optimization

Hey guys,

I resized my pictures with Bulk Resize Media and then I optimized them with EWWW Image Optimizer. Unfortunately most of my pictures don’t show anymore, so something went wrong.

Example: http://bit.ly/1FA2x8i

If I click on the broken image it opens normally and shows correctly.

What did I do wrong?

Thank You guys!
