I can recognize imagery when I see it but sometimes I actually want to ignore it because some writers overdo it. It's nice to use imagery every now and again. But I don't think it should be used constantly in every sentence.
Using a lot of descriptive words not only makes sentences very long but it's also tiring to read and think about. When imagery is used sparingly and intelligently, it flows and immediately conjures up an image in my mind. But if it's used a lot, I feel that the writer is a beginner who is trying to appear like a good writer by overusing imagery. I guess this is one of the things they teach to fiction writers.
