We're choosing an item from a list and then using ajax to populate a
view of the item, together with a listview of purchasable details.
For any given item there may or may not be images. Either managing
the relevant components in a page-level collection or using a visitor
to find them works. The key to the solution is:
1. they are all in a panel
2. that panel must be an ajax target
3. the logic to determine whether they are visible must be in the
onbeforereneder method of that panel
Thanks all.
