Version: (using KDE Devel) Installed from: Compiled sources OS: Linux If you start with a clean .kde4 dolphin does not show previews for pictures >1 MB. If you have a look at the settings the defaul file-size is 5 MB, so it should work. If one alters the value from 5 to e.g. 4 it suddenly works.
SVN commit 757802 by ppenz: Increase default preview size from 1 MB to 5 MB. TODO: it would be nice if PreviewJob would provide a static getter method for accessing the default size, so that applications like Dolphin - which allow to change the size - know the initial value.
