Following my recent post on optimal cover sizes for epubs
I have created an epub using an svg wrapper for the first time. I did try giving the cover image an id and put the height and width attributes for it into the stylesheet, but that didn't appear to work. However, with the attributes placed directly in the image tag the cover appeared without a problem in Sigil, and subsequently in iBooks on the iPad.
Is there somewhere on the forum where you can submit epubs for others to check to see if there are any issues on their (other) devices?
