Can I use Google images in the logo?
No, an image searched on Google is not yours, and the day a sign or a shirt carries it you may have to take it down. The mark is drawn for this venue or it is not a mark. If you are already using one, find every piece it is on: profile, menu, banner. Those are what have to be replaced, not only the file on the computer. In Madrid bars the stock icon shows up on another business on the same street. Besides the resemblance, the use is not yours.
An original mark as a vector, and the list of pieces where the outside image has to come off. It is not “fixed” by wedging the internet drawing inside a circle.
