Tall Boot help

So I bought these new tall boots today and I'm worried they're too short. They do dig into the back of my knees, but look really short. I know they'll drop a lot, I'm just worried they're too short already. I didn't pay much for them luckily, but I really wouldn't want to take them back. They are really nice compared to the others I tried on in the same price range... Anyway, any thoughts? Are they too short or ok...?

The photo you included isn't visible for me, just a link and a little red x in a box. The link that is there also doesn't link to the picture :)

It is a little hard to tell from the angle of the picture in the link you posted. From the side would be better.

Scratch my previous post, I can see it now on a different computer. I agree with countercanter, if you could get a side picture it would be a lot easier to give an opinion.
