How to avoid the image adds from the latest adsense code?

Hello friends,
How can I remove the image adds from the latest adsense code?
For the old type of code there is an option to remove it the image adds from the code itself.But I didn't see such an option in the latest version.
Can any one please help me to do that?

 

You can specify if you want to show image and text ads or just test ads in the first step of the Adsense setup.

 

I find image only ads pay more on my site than text ads, I get way better CTR, go figure

 

i think image ads would perform better on my site, maybe because the users play an online game? anyway i have all ads above fold images, and all below image/text.

 

You cannot change ad format of the new ads directly in Javascript code. Instead of it go to the "Manage Ads" section of your Adsense account, choose your ad and change ad format via "Edit Ad Settings".

 

I want to show only the text adds in my site.But I can't do it.
My site is techalone.
