Images appears lonely instead some pages

Hi.

An strange thing happens to some of my pages. When i try to see, for example:

http://myweb.com/mypage

i don’t see the content of my page. I see the photo of this page inserted alone in the page with the caption.

It is only happens in pages with photos and not in all the pages ¿?

I resolved deleting the fotos throught the media library and uploading again the photos with my ftp program.

then the page content appear again with the photo.

What is the problem?

Thanks!!
