Perhaps adding the name of the frame would help:
scaleImage(1,1,d)

but at the same time the default is to load an image at 100%, so if 
you're carefully sizing the frame, then this should be unnecessary.

Look at this piece of InfoBox.py that comes with 135svn:

        imageload = scribus.fileDialog('Load image','Images(*.jpg *.png 
*.tif *.JPG *.PNG *.jpeg *.JPEG *.TIF)',haspreview=1)
        im = Image.open(imageload)
        xsize, ysize = im.size
        new_height = float(ysize)/float(xsize)*new_width
        new_image = scribus.createImage(new_left, float(new_top), 
new_width, float(new_height),framename)
        scribus.loadImage(imageload, new_image)

First, there is the fileDialog to pick the image file.
Next, the script uses some commands from PIL, the python imaging library 
(requires 'from PIL import Image' at the beginning of your script). This 
loads the file so that the dimensions can be measured, then we use these 
to size the frame appropriately -- this script fits an image into a 
column to fill the width of the column.
Maybe this can be of some use now or in the future.
