RadFlowDocument export to pdf - images position on page

I have to put 2 tif images on same page, one is regular "check" size,  other is "T4" doc size ...
Page orientation is landscape I did calculation , resizes images, everything works great ... BUT
"check image" position is on the bottom of page ?

I need it on top of page. Tried all alignments etc but did not figure out .

 I attached PDF page [as JPG] .

This is simple class that produced PDF.
