I'm having a similar problem. I centered my image on my cover, but when I see the thumbnail of it on the Blurb website, it seems off center. Do I need to allow for certain margin or spine area for the cover, that's not indicated on the blurb template in InDesign?
how do I fix a cover page problem
in editing the page is centred perfectly
once uploaded it goes off centre
it is loaded in pdf
each time I have re edited the cover page and still once loaded the view you see is off centre

Hi there! If you use InDesign to create your book, the centre of the page lies between the book gutter and the black trim line. https://support.blurb.com/hc/en-us/articles/207792876
If you use Bookwright to create your book, you can move your image on the page until a vertical blue line appears, which indicates the centre of the page. https://support.blurb.com/hc/en-us/articles/207792656
