Hi Praveen,
Thanks for your inquiry. It could be that the problem occurs because the background picture has unsupported format. For example, Android 2 doesn’t support CMYK images. So, a red cross will be drawn if Android doesn’t support that picture. What version of Android are you getting this problem on?
Moreover, we have logged an issue in our bug tracking system for our development team to investigate this problem in detail. The ID of this issue is WORDSANDROID-183. Your thread has also been linked to this issue and you will be notified as soon as it is resolved. Sorry for any inconvenience.
Best regards,
