Steps to reproduce the problem:
1. Open theme .crx file in chrome
2. Allow to begin installation process
3. 

What is the expected behavior?
Theme should install as normal with specified background image

What went wrong?
That message popped up, and the installation stopped

WebStore page: N/A (my own theme)

Did this work before? N/A 

Chrome version: 49.0.2623.112  Channel: n/a
OS Version: 10.0
Flash Version: Shockwave Flash 21.0 r0

I presume this issue is because the background image has too high a resolution. I'm using the same manifest.json file as another theme, I've just switched which image is named 'theme_ntp_background.png', and am using a higher resolution image than before. What is the limit on image/ image file size?
