UITableView inherits from UIScrollView, thus you can in your tableView delegate receive UIScrollViewDelegate callbacks.

Implement the delegate method

- (void)scrollViewWillBeginDragging:(UIScrollView *)scrollView

which tells the delegate when the scroll view is about to start scrolling the content.

and 

- (void)scrollViewWillEndDragging:(UIScrollView *)scrollView withVelocity:(CGPoint)velocity targetContentOffset:(inout CGPoint *)targetContentOffset

which tells the delegate when the user finishes scrolling the content.

Read the ScrollViewDelegate Reference.

It is not a big deal you simply need to implement scrollview delegated methodes to know when scrolling stops ,Then set a bool value and reload the table and on basis of bool value you can show and hide the images.When scrolling starts set bool to NO.
