Thank you for contacting us.
I assume that the issue you described is related to this bug
in the ScrollView widget. The issue is already fixed and the fix will be published in the next Service Pack release which will be uploaded till the end of this week. Please wait until the Service Pack build is published, download it and test your application with it.
On a side note, is it necessary to change the ScrollView DataSource every time the details button is clicked? It seems that the extractPicturesFromGalleryScrollView always returns the same data items set.
