You are blocking the main thread with the following line of code:

cell.CellImageView.image = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:_ImageUrl[row]]]];

My suggestion would be to use AFNetworking and replace the code with the following:

[cell.cellImageView setImageWithURL:[NSURL URLWithString:@"http://example.com/image.png"]];

Also, your pointers should start with a lower case letter. For instance, CellImageView should be cellImageView.
