[m92] - new pdf reader - bug(?) in epub reading?

I have bought M92 last week, and I tried to read quite complicated ebook on it.
I tried to read with "new pdf reader" and cool reader.

Better for me was pdf reader, (citations, styles) but
1. it does not show some images in epub file - I *think* that it is related to fact that these images are referenced from file "gallery.xhtml" in images directory.
2. it does not rescale images in epub file, so some bigger images are shrinked

Am I missing something?
I tried to install latest pdf reader posted on this forum and, it looks like everything went ok. But how can I check pdf reader version?
