[build] /static

Apparently the engine statistics have been hidden from the images page when
infinite scroll was added as a preference in 56e34947a6

However, now that we also display engine statistics in the results page,
I don't see any reason why this should still be hidden from the images tab.

For example, this is very useful for seeing which engines work and which ones are broken.
