OPF file doesn't like "._"
This is my first post in this forum (probably the first of many). I am the ebook manager for a publishing Press called Ink Pen Mutations. I'm learning how to make ebooks,market them, etc. Not knowing much about this stuff I've been taking Lynda tutorials. The first ebook I'm making is fixed layout style from scratch.
I'm having a maddening problem trying to validate my epub. I'm getting this on all images:
WARNING: test.epub: item (__MACOSX/OEBPS/images/._12_homeless.jpg) exists in the zip file, but is not declared in the OPF file
There is a image file called "12_homeless.jpg". So, something seems to be putting "._" in front of all the images. I'm on Mac so I guess that could be the reason. But, I have no clue how to get rid of the messages. Any help would be appreciated!
