I don't know, why it should interfere with TG.
A possible approach for image buttons could be a custom widget that generates
an IMG tag with a special URL to one of your controller methods that generates
the image on-the-fly, doing caching, etc.
I.e. the template for the widget would look like:
<button id=${id} name="${name}">
<img
src="/my_widget_controller?size_x=${x}&size_y=${size_y}&template=${template}&text=${value}">
<button>
and the controller method my_widget_controller(text, size_x, size_y, template)
would return an image with the appropriate content type, possibly retrieved
from a cache (see the Python Cookbook for lots of caching decorators).
This could be slow though, since the browser would probably not cache the
image, unless you also set the appropriate headers in your response. I would
always go with CSS and background images, if at all possible.
