:::::It doesn't matter how Givewell describes themselves, it matters how others are describing them. We shouldn't be relying on primary sources to write the article. 
 :::::I agree that the article has too many irrelevant photos. The photo of the founder is relevant and useful, and should stay, but the others are only tangentially related to the content of the page. Using photos for the sake of having photos adds to the 'brochure' feel. (For comparison, this article has more photos than the significantly longer Médecins Sans Frontières does.)
