JQuery - making image stay and not disappear like in example
I'm trying to develop a simple shopping cart and using http://jqueryui.com/demos/droppable/#photo-manager as the base. However when I drop the Image I don't want it to disappear from the normal list. I've been messing around for the last day try to sort it and just can't figure it.
it's got something to do with the deleteImage function, I've removed bit and tried adding certain sections, could someone please point me in the right direction. Here is my source it's the same as on the site though:

Instead of this:
deleteImage(ui.draggable);
Delete the ui.helper
, which is the clone, like this:
deleteImage(ui.helper);
ui.draggable
is the original, so deleting the whole thing isn't what you want...the cloned image that you're actually dragging though, seems to be what yo're after.
