if you look here:

http://wiki.scribus.net/index.php/Infobox_in_column

you can review this script, which was made to insert a frame in a column 
of text, the exact width of the column. There was a kludgy sort of way 
that compensated for the lack of Adjust Frame to image, but what I 
eventually did is what you see below in this code fragment. The basic 
idea is to start with a certain width of the frame, then use the PIL 
(Python imaging library) to assess the size of the image and calculate 
an appropriate size for the frame.

         if (frametype == 'imageL'):
	    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)
