When I first started viewing images in MMS messages I always got a window asking me how I'd like to view them. Ex.: Gallery? Just this Once? Always?

Somehow I tapped the wrong selection and now all my images show small.

How can I change the defaults for this action?

I looked in Settings, Application Settings and looked at a few apps, but I can't seem to find the one that concerns viewing of images from other sources such as mms texts.

So annoying. BTW, there was a thread that answered this here, but it was from 2009 and the info is now out of date.

Thanks
