/*
* Known issue: Scanning browse pages with google chrome fails
* because chrome does not allow cross site xmlHttp requests.
* This is by design and I don't know of any workaround.
* Button displays appropriate message and is disabled.
* see http://www.chromium.org/developers/design-documents/user-scripts
* this might have been worked around by DA changing their server settings for origins
*
* When browsing a search/gallery and clicking a thumbnail to load full image
* on HTML5 browsers the GET button disappears. This is because DA hides
* the panel holding the button. Refreshing the page while viewing the single
* image will redraw the GET button allowing you to grab all images in the
* single image artist's gallery.
*
*
