2004-01-30 Chris Toshok <toshok@ximian.com>
+ * e-image-chooser.c (e_image_chooser_init): add an alignment
+ around the image. This might not be enough. hrm.
+ (set_image_from_data): handle the case where there's no image
+ (image_height == image_width == 0).
+ (e_image_chooser_get_image_data): new function.
+ (e_image_chooser_set_image_data): new function.
+
+ * e-image-chooser.h: add prototypes for set/get_image_data.
+
+2004-01-30 Chris Toshok <toshok@ximian.com>
+
* e-image-chooser.[ch]: abstract out the drag and droppable image
widget from the contact list editor and stick it here. There's
some code for a "Browse..." button here but it's not enabled.
