First things first.
What version of InDesign?
InDesign CS 5 - 7.0.4
1. Group the text and the image and then make it an anchored object.
2. Not sure what to do with that with CS5 but you should be aware that the use of audio and video in epub is very limited at the current time.
For Epub work you're far better off upgrading to CS5.5. In the mean time I suggest buying a copy of Liz Castro's excellent Epub Straight to the Point: http://amzn.to/rqNwkp
and checking out Anne-Marie Concepcion's videos on Lynda.com. You can get a one week free trial using this link: http://bit.ly/fcGpiI
Thanks for the suggestions and the info. I am just learning how to use this program to try to fill a client request. But what they want may not be possable...at least not yet. One question for you. If I have the items grouped, and go to the pull down menu and go to the anchor options, it will not allow me to anchor them. Is there something other than the objects that I have to have selected in order to allow for anchoring?
