You could try and use:

NSString* imgFile = [NSString  stringWithFormat:@"image%d",index+1];
NSString* pathToImageFile = [[NSBundle mainBundle] pathForResource:imgFile ofType:@"jpg"];
self.imgView.image = [UIImage imageWithContentsOfFile:pathToImageFile];

Indeed, imageNamed caches all the images you load through it. The cache gets bigger and bigger and it prevents memory from being freed appropriately.
