Getting Image Ads appearing in my adsense ads when they shouldn't!

[smn2]

Hi,

After being an Adsense publisher for a few years, strictly
text ads only, I relented and for one ad slot on one particular
site, I allowed images to be displayed.

(I believe the adsense code is

google_ad_type = "text_image";

.)

Since that time, about two weeks ago, I've noticed
image ads. appearing in other slots when, in my
opinion, they shouldn't.

But when I check the adsense code for these ads,
google_ad_type is not set at all.

So, anyone tell me how to prevent image ads appearing?

Do I really have to add the following to all of my ads

google_ad_type = "text";

Cheers,
Steve

You switch the image ads on and off from the Google Adsense online interface. You can't select them to be only on and off for particular ad sizes: the setting is global.

Cheers Nadim, but I don't think you're right

Within Google Adsense it specifically says (for my ads, anyway)

Ad Type Preference [edit]
AdSense will display: Text ads only in all ad units.

• You may override your ad preference on a page-by-page basis, by selecting the desired Ad Type option in your Ad layout code page.
Themed ad units disabled

I have overriden the ad preference in one instance, but am occassionally
getting image ads for other ads where I haven't done so.

email adsense support ..

then take a month's vacation and if you are lucky you may have a standard " please select your ad options from the interface.. text or grapical"

dealing with adsense support is like tossing coins down a well.. cept there's no satisfactory "gloooop" sound.

You may override your ad preference on a page-by-page basis

Maybe the page-by-page bit is the key and it's either on for a page or off for a page and not for each ad unit?

Steve, you are right. My apologies.

I've set ours in My Account > Ad Type Preference to "Text and image ads in all ad units." However, it does say "You may override your ad preference on a page-by-page basis, by selecting the desired Ad Type option in your Ad layout code page."

I don't care which ads show, whether they are text or image; just want the highest paying ones.

I noticed on one of my sites a very small image just to the left of the text ads. I didn't want to click it, but I poked and prodded at the URL and I believe it's some sort of addition that AdSense can put on for sites with a certain theme.
