//NSLog(@"Starting Size: %i", [imgData length]);
//Trying to push it below around about 0.4 meg
while ([imgData length] > 400000 && resizeAttempts > 0) {
resizeAttempts -= 1;
//NSLog(@"Image was bigger than 400000 Bytes. Resizing.");
//NSLog(@"%i Attempts Remaining",resizeAttempts);
//Increase the compression amount
compressionRatio = compressionRatio*0.5;
//NSLog(@"compressionRatio %f",compressionRatio);
//Test size before compression
//NSLog(@"Current Size: %i",[imgData length]);
imgData = UIImageJPEGRepresentation(largeImage,compressionRatio);
//Test size after compression
//NSLog(@"New Size: %i",[imgData length]);
}
//Set image by comprssed version
//self.pictureView.image = [UIImage imageWithData:imgData];
//Check how big the image is now its been compressed and put into the UIImageView
// *** I made Change here, you were again storing it with Highest Resolution ***
NSData *endData = UIImageJPEGRepresentation(largeImage,compressionRatio);
//NSLog(@"Ending Size: %i", [endData length]);
/* NSString *path = [self createPath:@"myImage.jpg"];
NSLog(@"%@",path);
[endData writeToFile:path atomically:YES];*/
[self startUploadingRequestWithData:endData andImage:self.pictureViewUpload.image];
