So, with that in mind, it's with great joy I tell you about my latest find: morgueFile free photos. They are high quality, high definition, and free to use - even in commercial products! It is good manners to credit the photographers anyway, but it is not required. The photos are honest-to-goodness free.
And there are a LOT of them too! The above are some samples I found when I
did a search on Spain. (There were over 900 photos tagged with "Spain"
by the way.)
I hope that morgueFile will be as useful to you as it is to me, amigos. And have a great weekend!
