Thumbnail Does Not Load

Hi everyone,

I am also having trouble with my images. The thumbnails to my posts do not load. Instead they have that evil blue box with question mark. I tried to download Post Thumbnail Editor but still could not figure it out.

Can anyone help advise who to resolve this tormenting issue? It has been the death of me.

Many thanks in advance!
