Sorry you are still having issues with this. The reason you are not seeing those slider images is because of JS errors from the twitter widget.
I can only do so much in this case. I was able to get my twitter account active on your site working with no errors as seen in the screenshot sent to you.
Sorry only way out is to send your twitter account password to check if you have setup the application right. There is no way out. Or you can try other twitter plugins out there on the wordpress plugins site and see if they work any better. Do let me know and I will do my best to help.
