One way is to call using

What you are asking is almost not possible.

Im saying allmost because it might be posibbole to

1. add a temporary contact to the address book with the phone number you want.
2. set its image to the image you want.
3. paste the call with the method you wrote.

but still there are 2 problems.

1. you will have somehow to delete the contact afterwords.
2. you can not do the things you asked from the background. and you can not do nothing when a call is active.
