The "go to Flickr page" is the default text for the linkLabel configuration option.
You can change the text used for the linkLabel by adding a line such as the following in your gallery's embedding code, before the fo.write("flashcontent"); line:

fo.addVariable("linkLabel", "Custom text goes here.");

When the link is clicked, the browser will be redirected to the linkurl for the image (set in the gallery's XML file).
If the linkurl is blank/empty or has been removed, then the link text will not be displayed.
