Help! Why did Google remove my images from their index?

[shawn81]

I've been scratching my head over this one for a while now and I can't seem to figure it out.

I own a website that is user-generated content. Users submit images to my sites of graphic resources (for designers) that they have created to share with our community.

I've been noticing over the past few months that I'm getting completely dominated in Google Images. I used to get a ton of traffic from Google Images, but now I can't find my images anywhere.

After diving into Analytics I found this: http://cl.ly/140L2d14040Q1R0W161e and realized sometime about a year ago my image traffic took a dive.

We've gone back through all the change logs and can't find where we made any changes to the site structure that could have caused this. We are stumped.

Does anyone know of any historical Google updates that could have caused this last year around the end of April 2010?

Any help or insight would be greatly appreciated!

Well thanks for your feedback, but your answers really have nothing to do with my question. This happened in April 2010 which was well before panda.

Some guesses for you:

Your first thing at the top is an ad.  This is not really useful content for users.  Google Panda may or may not tolerate it.

On a related note, since you don't have much text, perhaps it appears to google like you don't have much overall content and are stuffed with ads, which is definitely not tolerated by Google Panda

You don't have an address, a phone number, or other trust factors on your site.
