img_div

You can tell Zogilib not to use the whole window for displaying the image.

img_div(side=200) - the image width will be 200 (px?) less

img_div(bottom=200) - the image height will be 200 (px?) less

head_js

You can give Zogilib additional url paramters by calling head_js with new parameters: python:here.head_js(newparams=[('param1','something',1),('param2','somethingelse',1)]).

newparams=[(parametername,parametervalue,importance)]

If you set importance to '1', the parameter will be added to each url.
