I use the http://www.myaudioschool.com website. I paid the $15/yr subscription fee and have all of Beatrix Potter’s books for audio. It does include some pictures on the website, but not all of them.
Also, alot of the books recommended here and by Ambleside are found on http://www.mainlesson.com and those can be downloaded. I don’t know if they have illustrations or not.
I have a few Bibles on my Itouch and the program Daily Audio Bible which has been the only way I’ve been able to be in God’s Word for the past few days. I’m so grateful for it! Also, at the http://www.faithcomesbyhearing.com website you can download the whole Bible dramatized (and with songs) for children for free! There are lots of fun resources out there.
Since I’m a newbie with all this, I will wait and lurk and see what others suggest to you.
