Vunda Von created CB-4987:
-----------------------------

             Summary: IOS 7 Phonegap crash when rendering images
                 Key: CB-4987
                 URL: https://issues.apache.org/jira/browse/CB-4987
             Project: Apache Cordova
          Issue Type: Bug
          Components: iOS
    Affects Versions: 3.0.0
         Environment: IOS 7, iPhone 5s, Cordova 3.0
            Reporter: Vunda Von


I have an infinite scrolling list in which the user scrolls to the bottom and new items load
from the database.  I am properly removing any object and image from the DOM however that
is not in view.  I unload images by setting their src to an empty string.  I have monitored
with Instruments on the Mac and I can see the memory constantly being collected and never
peaking about 25 MB.  My problem is random, when rendering a new page from infinite scrolling,
if it is heavy with images, it crashes.  Here is log from the thread that crashed:

Images are about 900px width and resized with css to about 400px.  There are no shadows or
fancy css3 effects on the images.
