web2py How can I use images in radiobuttons generated from a SQLFORM -

i generate sqlform radiobuttons using radiobutton widget below (code trimmed):

db.define_table('taba',     field('name', 'string', length=16, required=true, unique=true, ),     field('shape', 'string', length=8, default='star', widget=sqlform.widgets.radio.widget, requires=is_in_set({'star' : '<img src="/myapp/static/images/shapes/star1.png" />'}))) 

my problem image code above gets sanitized , image tag doesn't show up. can turn off sanitization sqlform somehow? or there different elegant solution this? code above shows 1 radiobutton item simplicity, items generated dynamically.

you can replace '<img src="/myapp/static/images/shapes/star1.png" />' 1 of following 2 options:

• xml('<img src="/myapp/static/images/shapes/star1.png" />')

• img(_src='/myapp/static/images/shapes/star1.png')

also, preferable use url() function generate outgoing urls. replacement, above 2 options change to:

• xml('<img src="' + url('static', 'images/shapes/star1.png') + '" />')

• img(_src=url('static', 'images/shapes/star1.png'))

for more information, see online book topics on xml() , img helper.
