Understanding featured image import

i installed Autoblog, and i can't seem to make it work the way i need it although i see that all the options i need are available with this plugin.
What i need is this:
make my front page show posts from all other Multisite blogs. I want them to show the featured image (it won't import it although i activated the option), and to keep links from the excerpt if there are any. All other options work fine, i just don't understand what to do with Featured Images in terms of settings, and how to keep links inside excerpts.
Also, i only use the plugin for my main Multisite website, so should i activate everything locally or network-activated?
Thank you!
