I use imagegen.ashx to resize images on my Umbraco 4.7 website. It is by default disallowed in robots.txt and images for which I use the handler do not appear in search engines results - I have checked in Google Webmaster that they are blocked. I would like to allow this images to be searched.
- Can I achieve this by allowing the imagegen.ashx in robots.txt?
- I also would like to know is there any good reason why it is disallowed by default?
- And if I make it allowed would it resolve my problem with blocked images or it requires some more configuration changes?
