I don't think 180 views is a small number, considered the big amount of posts made daily. A suggestion maybe put the underrated image as one of your 3 displayed on the frontpage of your homepage, so whenever someone got there, they'd see the thumbnail and possibly click on it. Other than that... imagine if every poster would post a thread in the forum pointing at whatever image they feel the need to boost... It would became a big mess and probably very few would keep on using the forum. In any case you can always repost your image... Btw, i saw part of your gallery... pretty nice works there!
