The following table show the servers status.
I must have the same table. if one image changes I must issue a warning.
How can I check all the images in the table?

At first I must write a javascript code which replace the image to Ok.
Secondly I use the webScraping to extract all data.
To invoke the javascript code we must use “inject js script”
