I do not know how to delete the photo's programmatically.
(But everybody knows how to save.)
iPhone  app has access to the files in its sandbox.
Can you save the images in the application document folder? So then you can delete it using the standard file manager?

NSFileManager *fileManager = [NSFileManager defaultManager];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask,  YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *fullPath = [documentsDirectory stringByAppendingPathComponent:name];

NSError *error = nil;
if( [fileManager fileExistsAtPath:fullPath] )
        [fileManager removeItemAtPath:fullPath error:&error] );

Here is a blog post with save and remove code:

Maybe, you can find something in the open source iphone browsers?
