images and caption for epub

Hi,

I have a lot of pictures with captions in my ebook and want them to appear together on the same page. My pictures are anchored in the center of the page so are the captions.

I tried to group them but still the image and caption appears most of the time on a separate page.  I even tried to put the caption on top of the picture but still the caption and image are on a separate page.

Any idea?

Thanks a lot!!
