As Nebraskon was this weekend, I decided to code instead of art. So...
Anybooru Slideshow (Windows Sidebar Gadget)
Site Page: (Which I desperately need to update)
-Defaults to Danbooru
-Default queries 'animal_ears'
-Default delay 30 seconds (any less and you risk getting banned from the site)
-Safe search on by default (program side instead of query side, otherwise it would waste a valuable tag in Danbooru's 2 tag limit for normal members)
-Options are saved as long as you don't remove the gadget. (Each instance of a gadget has its own settings)
-Clicking on the displayed image opens a flyout of the past 5 images; clicking on an image on the flyout opens the /show/ page.
-Shouldn't freeze (I've added in a few try/catches at the most problematic sections) but if it does simply kill the gadget itself and start it back up.
Anyway, thanks again for the help!
