That is basically what happens if you omit the alt attribute altogether. 
My graphical browsers (when I turn off images) write "Image" in place of 
the image to alert me that there was one there. Presumably aural 
browsers do something similar, telling the user that there is an image 
present at this position in the document.

Also, your text is not particularly useful to someone with limited or no 
vision. It might as well say alt="(Use eyes that work properly to view 
this image)"

I expect that the browser-generated placeholder is more useful in almost 
all cases.
