Hi,

Because I don't have any books which have PAGE sections, I have just tested about HD image extraction of the exerimental version.
It seems working fine to extract HD images.

I have researched kindlegen's condition to shrink images.

The condition to shrink file size is that the size of image is larger than 819200(=800x1024)bytes perhaps. And one image's resolution is shrinked from 1600 x 2400 to 1347 x 2021 , the condition for resolution shrinking is unknown (not just from the file size). When srinking resolution, the html is not modified, so width and height in tag become not correspond to the image.

The followings is the result,

filename , source, in Images folder,
image0.jpg, 909934byte, 773356byte, has HD image
image1.jpg, 1298376byte, 365360byte, has HD image, shrinked to 1347x2021
image2.jpg, 1572736byte, 770304byte, has HD image
image3.jpg, 826567byte, 741256byte, has HD image
image4.jpg, 816893byte, 816896byte,
cover.jpg, 1645305byte, 770856byte, has HD image

I attach the test mobi.
