+commit 0254a5942b7ff18bf0072db3ebcd591512d99a10

+    Fix showfoto usability.
+    
+    This resolves issue #50.
+    
+    The problem seems to be a known issue already addressed by the original
+    authors. This is an extract from the 'ChangeLog' file that best
+    describes the issue:
+    ```
+    Fix a linking problem with showfoto, image plugins and
+    --enable-gcc-hidden-visibility:
+    All image plugins link to libdigikam.so.
+    The showfoto executable however does not link to this lib, but
+    statically links the relevant parts.
+    With visibility hidden, now the linker obviously cannot see the
+    already linked DImgInterface class,
+    and there would be two different static variables for
+    DImgInterface::instance(). One with the loaded
+    image, the other (from the image plugins) with a null image.
+    ```
+    Linking against libdigikam.so instead of including the libraries in a
+    static way solves the issue.
