As reply to rourris post (maybe you have a similar situation as I do) or to anyone who has a similar situation: In case all your pictures in the note have the same dimensions (mine are all coming from the same digital camera), Evernote will choose the thumbnail based on the order, in which the pictures were inserted into the note and not based on the order of the pictures within the note. So, if you have two pictures of the same dimensions <picture1> and <picture2> and you want to create a note with the two pictures in this order (<picture1>, <picture2>), but you want <picture2> to be the thumbnail, then first add <picture2> into the note and then add <picture1> above <picture2>. This way your not will be "some text <picture1> <picture2>", but <picture2> will be the thumbnail. As soon as the two picture have different dimensions (which probably is the case when they are coming from different sources (web, photographed, scanned)), the largest-smallest algorithm will perpetrate its despicable crime....
