Blog Cover Image & Page issues after EB update

Hi SI Team

I just updated to the latest EB version.
Two things I am noticing.

a) There is something weird happening to the cover images:

Please see the screen shot.

b) Whilst I love the idea of splitting a Blog post into pages… I need more control.

e.g. the first article linked above is split into 9 pages!
How/where can I adjust the length of these pages?
e.g. instead of 9 pages 3 pages?

thanks

Paul
