how to get position of tumbnail right at front-album

It looks like there’s several <br> tags being added inside of the album link, specifically between the anchor and the <img class="Thumb" alt="Bierstube" — deleting that element in the browser inspector fixes alignment for me.

NextGEN’s templates don’t include any there, I would check which template your compact albums are using or for other plugins that may add a series of anchors with the class “fbx-link”.
