W2E is not a file converter, but an ePub creator.
This means that some formatting used in documents, expecially in Word documents, can be lost.
When you create a document for W2E, please take care to use only the supported styles, avoid frames (is probally the cause of the image border problems) and keep clean the text as possible.
Many feuture often used in .doc files are meaningless in ePub, and can create problems in W2E.
Anyway, sending to me the original files causing problems can help to solve bugs.
