Hi Claude31, tanks for your reply. Manually I just tried and it doesn't work. I'm not getting a past function by doing a right hand side click or a png file by using the shortcut "command v". The point is: I like to make automatically a collection of screenshots from the moment on, when the connection to my cloud isn't available until the connection is back again, controlled by a timer with let's say 5-10 Minutes. The collection then will be converted to one! pdf file manually via Adobe Acrobat DC (which is very easy) as a proof for the connection quality. The screenshots capture the time, date and the status "offline" or "online". The information based on the fact that the connection to the cloud was lost, I'm getting through the E-Mail my app is generating on the two moments "offline" and "online". Therefore I need all the png's. Best Thomas
