Using a watermark image fails with exception

[freemarkus]

I try to use a png image as watermark (by setting PHOTO_WATERMARK_TEXT = '' and PHOTO_WATERMARK_IMG = 'image.png' in pelicanconf.py). This results in an exception every time an image is processed.

[21:23:04] ERROR photos: 'float' object cannot be interpreted photos.py:1786
as an integer

The version installed is 1.6.0.

At a first look, the assignment to mark_position in plugins/photos/photos.py lines 1355 to 1358 seems to be wrong as it consults text_size. The plugin seems to work as intended if they are commented out.
