Sally up to yesterday I would have been in agreement with you. I also received that message asking me for the millionth time to add image ads and text instead of just text. I was going to ignore it but the previous days had just been too crappy so I took a chance. I set all my ads to image & text last night and by 5 am this morning I had made almost the daily average. I was shocked. Never believed in image ads. I don't know if there any auction behind the whole thing but it sure appears to be working for me. I had tried image ads by themselves before but never both.
