20 Mb as a PHP memory limit?
This is too low. You need to increase to 64 - 128MB

Hello Sir,

But how can I upgrade to more than 20MB. Thanks

You need to ask your hosting provider to do this for you.
Furthremore you can try increasing the "Enforce memory limit (in MBs) for image processing" setting in K2's options (images tab).
