[ITK] [ITK-users] storing images in a list

[Tim Allman]

By mistake I sent this to Emily personally and not to the list. So, list, here it is.

Emily,

You have not yet added anything to the list so the list is empty and the iterator begin() is the same as end(). There is nothing yet in the list for begin() to point to so you are trying to insert an image using an invalid iterator. If you were to do something like

lmImages.push_back(image);

I’m sure it would work.
