We'd like to run a scan on our site that returns a report with the following:
Is there a simple tool that does this? We're attempting to check for alt attributes, and make sure the alt attributes accurately describe to the image they represent. That's why the visual representation in the report is important.

What to do (in short) To fix an Image Missing Alternative Text error, you will need to add an alt tag to the image with appropriate text describing the purpose of the image in the page. If the image is decorative, the alt attribute can be empty, but the HTML alt="" tag still needs to be present.
The required alt attribute specifies an alternate text for an image, if the image cannot be displayed. The alt attribute provides alternative information for an image if a user for some reason cannot view it (because of slow connection, an error in the src attribute, or if the user uses a screen reader).
Try the Python package Beautiful Soup. It will parse all of your HTML for you in a really simple statement. Try this code:
website = urllib2.urlopen(url)
websitehtml = website.read()
soup = BeautifulSoup(websitehtml)
matches = soup.findAll('img')
for row in matches:
print row['src']
print row['alt']
From here use row['src'] to set the src of an image and print out alt next to it.
