I'm not sure if this is a problem with Imce CCK Image or with Vertical Tabs, so I'm adding this to both modules' issue queues. This is my situation:

I have created my own node type. In this node type I've added a Imce CCK Image field.

If create a new item of this type I can add an image and everything works fine. However, if I include the image field in the Vertical Tabs part of the page, the image is lost. I don't think it's saved at all.

I hope this is enough of a problem description.
