Justification Goes Haywire

Today I inserted an image as a link. For that image, in a paragraph by itself, if I clicked on the Center justify button, it moved to the left margin, and if I clicked Left justify, it centered. If I clicked right justify, it moved even further to the left.

Also, compiling that chapter resulted in some images missing.

I deleted the image, and reinserted it and it seems to be OK, but currently none of my images are centered in the compiled out (separate problem)?

Please let me know if there is something I did wrong in case it happens again.
