Word of advice. If you wanna take images from tumblr, change the end of the url (whether .jpg or .png it doesnt but it doesn't really work for .gif) from the number 500 to 1280 for full size. And if that doesn't work, leave it as 1280 and change the first numbers in the url from 40 to 41, 42, 43, or 44. Or vice versa from those to 40. Gifs are tempermental so I leave those alone. Another way is to just click the image and whether it expands or brings you to another url (usually on single images do this) it doesn't matter because then you just right click then click open image in new tab. Hope this helps :D
