A solution (if one is needed), could be to simply add a slightler darker block background to the Wiki row.This looks quite bad IMHO since it doesn't fit in at all.
I think the main problem is however that the huge book with it's contrast is so much attention grabbing.The "problem" is probably more general, ie. images are not very consistent in style and size on this page.
Another possible solution would be to create a more obvious zigzag by overlapping the horizontal range of the textsThis could work as well.
The book does look like it belongs to the forum section. I do like your aligned version; it's much neater. However, for interesting aesthetics, the zig-zag wins.
