replaced the loading method with its call to a lower method that passes in the same valued, with the exception being the target size. In the previous call it was sending a CGSizeZero for the size, which when going through the React_ImageLoader, would load the whole image at full size, but also make a uncompressed version of that image as a CGImage, which would then be transformed and resized buy the method, but by passing in the desired target size here, we are able to load the image in the correct size and be lighter on the memory usage for large images, and then the rest of the transform can take place.
