Answer 1

You can achieve it, By knowing the names of your images, so while you are storing your image you need to store some information of these images in database,(or some where you can use it), then fetch name of image from data source, and work as follows:

NSString *str = [NSString stringWithFormat:@"%@.jpg",[myGlobleArrayOfImageNames objectAtIndex:imageCounter]];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *fullImgNm=[documentsDirectory stringByAppendingPathComponent:[NSString stringWithString:str]];
[mainSlideShowImageView setImage:[UIImage imageWithContentsOfFile:fullImgNm]];
