They say an image is worth a thousand words. And when it comes to picturing the extent of the churn happening at the top of Twitter, three images shared on the social media platform this week (where else?) help illustrate how many faces are changing at the top of the struggling company.

On Monday, Twitter CEO Jack Dorsey confirmed in a tweet that four executives -- senior vice president of engineering Alex Roetter, vice president of human resources Skip Schipper, vice president of global media Katie Stanton and senior vice president of product Kevin Weil -- had "chosen to leave" the company. Jason Toff, the general manager of Twitter's Vine service said separately he was returning to Google. The move follows other relatively recent executive changes; Dorsey also said Tuesday he's adding a chief marketing officer, the American Express executive Leslie Berland.

To make sense of the churn, Goldman Sachs analyst Heath Terry put together a handy chart chronicling the executive turnover at the company in recent years, pointing out that the list is not, as the tweet below says, meant to be complete. Noting the company has "experienced elevated levels of executive attrition," Terry's list reminds investors the company has not only had two CEOs since its IPO in late 2013, but three chief financial officers, three engineering leads, and lots of change in product management. (A Twitter spokeswoman said in an email that the company did not have a comment to add beyond Dorsey's tweets.)

Pictured another way, BTIG media and technology analyst Rich Greenfield had his own image to share, this one of all the people who've headed up the product teams at Twitter since 2010. There have been five, and Greenfield adds in Dorsey, who said Monday in a tweet that chief technology officer Adam Messinger "will be taking over all of engineering and consumer product," as well as other responsibilities, but that "I will be partnering with him day and night to make sure we're building the right experiences."

A couple days earlier, Greenfield had another image to share -- this one of the executives who presented at the company's analyst day in November 2014. With large red "Xs," he crossed out how many are now gone, pointing out that only five of the 13 remain.

Of course, the most interesting picture to see will be what all these changes mean for the company's stock chart, particularly at a place still working to prove itself to investors. While fresh blood is helpful sometimes, research has also shown that too much executive turnover can hurt firm performance. Twitter shares are down about five percent this week following the news.
