Create a link to a image or to a link passed as argument

This function is called after link_to which does the same thing except that instead of a label, it render a link with an image literal.

def image_to(src, alt, url=None, width=None, height=None, **attrs):
    src = url_for(src)

    if url:
        url = url_for(url)
    else:
        url = src

    return link_to(image(src, alt, width, height, **attrs), url)

I forgot to write how tu use the function. I guess it’s pretty simple

With image source and alt attribute:
h.image_to(’/images/something.png’, ‘Something’)
>> literal(u’’)

With image source, alt attribute and link url
h.image_to(’/images/something.png’, ‘Something’, ‘test.html’)
>> literal(u’’)

Same thing as above with url_for
h.image_to(’/images/something.png’, ‘Something’, h.url_for(controller=‘event’, action=‘view’, id=4))
>> literal(u’’)

I don’t know if there is a better way to do it like, I guess the url_for in my snippet is useless.

def image_to(src, alt, url=None, width=None, height=None, **attrs):
if not url:
url = src

return link_to(image(src, alt, width, height, **attrs), url)

Loved to read your blog. I would like to suggest you that traffic show most people read blogs on Mondays. So it should encourage blogger to write new write ups over the weekend primarily.

He fet una gran quantitat de campanyes d’investigació de mercat d’aquesta manera i els resultats són bastant sorprenents. La gent se sent important, ja que han pres el temps per fer-les. I el més important, vostè rebrà valuosa informació sobre exactament el que el mercat vol i no el que creus que vols.

Mobile advertising and marketing is the easiest and the least expensive approach of selling as now we can see that many suppliers supply inexpensive cost for texting. Men and women all the time hand a mobilephone too everywhere. tempurpedic
