should help you out The best solution is to cache your images. You only make the asynch request if the image is not in your cache. If you have the image in the cache then just show the cached image. While you could just hold a dictionary of [String : UIImage] and use the URL's as keys, this isn't very memory friendly or bandwidth friendly since its not persisted. You can write a much more sophisticated cache, but other people have already done it so I suggest just using one of theirs: SDwebImage AlamofireImage

should help you out Setting the backgroundView of the tableView to a UIImageView results in an image that remains in a fixed position.
code :
UIImageView *backgroundImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"background"]];
self.tableView.backgroundView = backgroundImageView;
[backgroundImageView release];

I wish this help you Is it possible to load all cells of an UITableView when the view is loaded so that they are not loaded when I'm scrolling? (I would show a loading screen while doing this) , You can cause all of the cells to be pre-allocated simply by calling:
code :
[self tableView: self.tableView cellForRowAtIndexPath: indexPath];

it should still fix some issue In your cellForRowAtIndexPath method, set your cell's background color to clear color. It will make your cells transparent and show the background image.
Objective C:
code :
cell.backgroundColor = [UIColor clearColor];
cell.backgroundColor = UIColor.clearColor()
