First broken link fixed.
The item Graphics -> Drawing Bitmaps
in wiki page Articles Tutorial
was pointing to tutorial Displaying Images
made by Jason Oakley (that's the original URL: http://bluebilby.com/2013/04/14/gideros-mobile-tutorial-displaying-images
I retrieved content of Jason Oakley' tutorial from webarchive.org and put it in a new page named Drawing Bitmaps
that I created in the wiki.
Finally I edited the Articles Tutorial
page so that item Graphics -> Drawing Bitmaps were pointing to the new page.
Of course I put a note on the page giving all credits to the author with a link to their profile in his own web site.
I'm planning to do the same for all broken links.
Let me know if you have something against it.
