Loading issues with embedded UIImage in cell

[red]

I am displaying thumbnail images from a server in a UITableView. Each cell has three images horizontally, about 10 cells total. Problem is: The image gets loaded from a call within an subview of the cell's content view when the cell is drawn in the table. When the table scrolls down and then back up the cell is removed then added again but the image is not there and the image is loaded from server again. This is a lot of extra loading obviously (I have not implemented NSURLCache yet)

2 Questions:
1. Can I force a cell to reuse the same cell that it used before and keep it's loaded subviews? Or maybe change the number of cells that are kept in memory?
2. Is there a better alternative to UITableView for this?

PHP Code:

[cell.contentView addSubview:thumb.view];

Bump.
This is important to me
