thanks for that, where are the arc & series zips mentioned above?

Do you have a current link can't seem to find the arc links etc...?

I have a workaround but it is very labour intensive. would it not be fine to have the option to grab the bottom right corner of a book and 'fit' it into the given shape, which would either be stretched or squashed to a greater or lesser extent? this could sort out double page spreads in comics too?

is there/could there be a way to bookmark series as well as individual comics?

I take it publisher icons go in each seperate publisher folder as a folder.jpg. 

making some new publisher logo icons, not all are mine and i'm working my way through

spot on, cleared cookies and site data in chrome, book count and green selection dropdown appears. thanks Scott

did this tell you anything?

Nice, I'll start doing that

Completely solved this, more or less as described above. 

using calibur, import your books

select all, download meta data and covers

select all, resize cover (this is a plugin) I use 300x432px (the ubooquity max i think)

select all, bulk convert, to epub

point your ubooquity server at your calibur database or copy all books to where you normally store your books

clear database in ubooquity

VOILA, all perfectly sized books
