Increase in indexed images?

[Rumbas]

I have for a long time not been able to get all the many images on the wife's two blogs indexed. Google would only grab a fraction of them.

A while ago I just for the fun of it clicked resubmit button in WMT on the image sitemap (Wordpress + Yoast plugin) and Google grabbed almost ALL of the images shortly after.

Traffic from image searches seems to increase somewhat the last few days.

Anybody experienced anything similar?

Just yesterday, I noticed a beefier image insertion in the serps for some obscure kws. I shrugged it off as just happenstance, but I'll mention it here just in case.

Now that they're indexed, how about stuffing the iptc caption field with some kws?  You know, for science!
