More information (it's just a fast translation, so feel free to fix the grammar ;>)
* the photos have to be taken by Wikinewsies or Wikimedians and must have been published in 2007 * they have to be used in any of the articles of the Polish-language Wikinews * there are two rounds: the first one from January 28th (0:00 UTC, as I take it) to February 3rd (probably 0:00 UTC, too). The second round takes part from February 5th (0:00 UTC) to February 12th (0:00 UTC). * in the first round every user contributing to Wikipedia, Wikimedia Commons, Wikinews or other projects of the Wikimedia Foundation is eligible to suggest a candidate and vote, but if (s)he does not have an account on the Polish-language Wikinews, a link to a userpage on a chosen project of the WMF must be provided. * in the first round, you can approve as many photos as you want, but you can only vote once on one photo. * only 5 photos with the highest number of votes -- and only one photo from a single article -- will pass to the second round. * you can only vote once in the second round.
Hope that makes the situation a bit clearer.
Best regards,
