Title: Implemented Proposed Fix for #548

I was having the same problem as sylvainlaurent and implemented the fix suggested in the comments.

Tested uploading several images and they no longer remain allocated after the request completes.

It does, however, seem to be the case that if the application goes into the background before completion, the memory is not released until the app is relaunched - but it will release.
