Did you create them yourself, of so, do you still have the file (PSD or whatever) you created them in? It would be much easier to do this, without the text in it, as that complicates things a bit.
No, I did not create them. If so, it would be easy like you say. I googled "Facebook icons" and "twitter icons" and picked these two because they matched. That's why I need two more made because I wasn't able to find one for AIM and Skype. Thank you for your comment and for viewing my thread.
Did you find similar icons on your journey, ones with the same background, but without the text?
If so, you could do it yourself in Preview.
