something like Cheetah might help here:

 >>> from Cheetah.Template import Template
 >>> t = '<img src="$image">'

 >>> data = {}
 >>> data['img'] = 'foo.jpg'
 >>> def image(): return data['img']
...
 >>> T = Template(source=t, searchList=[{'image':image}])
 >>> T
<img src="foo.jpg">

...or you can access "img" directly in the template:

 >>> t = '<img src="$image.img">'
 >>> data = {}
 >>> data['img'] = 'foo.jpg'
 >>> T = Template(source=t, searchList=[{'image':data}])
 >>> T
<img src="foo.jpg">

say that "data" changes, you don't have to compile the template
again, just issue a render command again:

 >>> data['img'] = 'BAZ.jpg'
 >>> T
<img src="BAZ.jpg">
