I sure can... The issue, as it is and I am sure you have noticed, is that getting the list of contacts takes a long time. For the thumbnails I created a "cache" so the application can display them right away. I am hopeful that a new release of qt mobility will speed things up or I may be forced to replace it.
Right now the easiest way is to just edit the contact on the standard contacts application and assign an image to the contact (it can be any image - like one of the 3d avatars). Next time you hit the reload button on "myContacts" it will add the new contact to the thumbnails view. I want to avoid editing the contacts on the "mycontacts" application for now.
That is an interesting idea that I didn't think about. I will see what I can do about it. Please keep them coming !
