Who says image streaming has to be done in English.

If you want to improve your English just do it. Hesitating looking for the right word is an excuse everyone uses it doesn't matter if they have a big vocabulary or not because we are going back to the beginning and looking at the picture and trying to put it into words just talk to the right description. You're describing it for someone who cannot see it and fancy words don't help. They say a picture is worth 1000 words... so start saying the words that describe the picture and as you do more will come.
