French publishing and ad group Hi-Media, which bought photo-sharing site Fotolog for about $90 million last year, is now making changes at the top. General manager Andrew Cohen is moving out of the picture and being replaced by CTO Arne Jokela and senior product management director Yossi Langer, who are stepping up to each get a “president” role while also retaining their old responsibilities.

Hi-Media doesn’t say why it’s making the switch for the New York-based site, which claims 15 million registered users and is strong in Latin America, though CEO Cyril Zimmerman, in the release, offered: “We’re casting a vote of confidence by promoting senior managers to take Fotolog to the next level. We know Arne and Yossi can lead Fotolog’s development, a major part of our strategy to build a global integrated online media company.” Langer will focus on the revenue side, which makes the position of chief revenue officer Eglantine Dever also unclear. Hi-Media’s plan for Fotolog is to integrate it with its other properties; it recently bought stakes in sport.fr, vivat.be and rue89.com and also bought music site Magicrpm.com.
