Image size and overall ebook file size

I have successfully created a printed book some years back (THANK YOU Lulu!!) and am now working on my next book.
My plan is to start with an ebook and then later publish a printed version. My book will have quite a few black and white images. I have three questions.
1) What is the optimum size for an image?
Right now I am creating the images 4" wide at 200 PPI (800 pixels wide, height varies from image to image).
2) Is there a maximum file size allowed for the completed e-book?
I am barely into it and the total file size is already 1.2MB.
3) Is there a way to test the completed e-book on various platforms?
I use Calibre on my desktop and iBooks on my iPad mini. After some problems that evidently had to do with image size, I have been able to view my partially completed book on both platforms.

As for file size, I wouldn't put much emphasis on that yet. If you get into the 200-300 mb range, it might be time to consider compressing some images or lowering the resolution, but EPUBs do compress everything, so a 200 mb Word file can convert into a much smaller EPUB file.
Once you've got the entire interior prepared, upload and convert to EPUB, then test it on as many platforms as possible. Digital Editions (Kevin links to this above) and iBooks are generally the two most important to test. If your ebook looks good on Digital Editions, that should mean it will translate to Kindle without issue.
