1. I can't help with the blinkies! I always hire mine out, I'm no good at that stuff!
2. In most programs, if you hold the shift button when you are resizing, you should maintain the size ratio of your documents. I suggest using the crop tool to crop your papers down to 8.5x11 and the resize tools to adjust elements. As long as you always make them smaller and not larger, the resolution should not be affected. If you need further help or a tutorial written, send me a PM!
3. I have some brag book sized templates in my store, some are 4x6, some are 5x7 but you can crop them down to 4x6 easily. My store is here: http://www.digitalscrapbookingstudio...x&cPath=13_203
4. I don't know how to do animation like that, I'm sorry!
