I would like to know if anyone can verify this weirdness, or explain it to me in Noddy language.

A long time ago (not sure HOW long, at least 18 months) I modified the Calibre template and stylesheet. Specifically, I swopped publisher with tags in the template, and had no "label"/"pubdata" TD. I modified some colours and font sizes in the stylesheet.

All has gone fine until recently, when I discovered that inserting a jacket using Modify epub (as I always have done) resulted in my Android reader (Mantano on a Nexus 7), Firefox (plugin) and Adobe Digital Editions all reading the jacket data table as left-aligned, all black, all serif - ie disregarding everything but the retrieved data (title, author etc.). The jacket is read as one would expect by the Calibre epub viewer.

I assumed (naturally, since my knowledge of html is pretty basic) that I am an idiot - although I had not touched the template and/or stylesheet since the long-ago modifications - and that I had done something wrong myself. Many uninstalls and reinstalls of Calibre (trying both 64 abd 32-bit) and Modify epub later, I have found this:

The same jacket, using the same template/stylesheet, whether the Calibre defaults or my own:
-- is "seen" as expected when it has been inserted with a Calibre conversion
-- is "seen" left-aligned, black etc. when replaced/inserted using Modify plugin
-- this is true with all the readers mentioned above, except the Calibre viewer, which has always read and still reads the jackets as expected

To triple check all this I unchecked ALL options in Modify epub except Add/Replace metadata jacket. I have inserted/replaced a number of jackets using both the plugin or a conversion, and the results are consistently: Calibre conversion fine, Modify epub wrong,as described.

Comments? Thoughts? Advice??
