For some reason using an image within an html e-Mail (inline attachment) did display correctly in my rails application. Instead the attachment was displayed as a "normal" attachment in the attachment section of the E-Mail client.
Usually we enter "keyword" or "terms" in web search engine (google, yahoo, bing, etc.). But then what if we have an image, and we would like to search the web pages or web sites that contain that image (or similar)
