As TM Images is not part of TalkMorgan, I cannot resolve this directly,

However, I am confused - is it one image on the Image site or is it all that AVG don’t like? If it is one, and that image is someone’s avatar, for example, I can delink that in their profile, hence it should stop the AVG software blocking that particular image. If, however, it is all photos from the image site, I can’t help and that will be down to AVG or the owners of TM-Images to resolve.
