This still seems to be an issue on 0.1.4. We are changing the uri of the image, but it does not reload. I have checked OfflineImage.js and the code changes listed above are there, although 1 line is different....

if (nextSource && source && nextSource.uri !== source.uri){

I put some logging before that if statement and noticed that nextSource.uri and source.uri are showing as the same value, even though I change the value
