And where and how in the application to create your P1_HELP variable so that it would be possible to use, for example, src = "# P1__HElP #" in the HTML code without bothering with javascript?
I want <img isrc="P1__HElP" width=600 height=400> where P1__HElP = http://placehold.it/350x150 , To open a photo, depending on the power that is written in the variable. I will be grateful for your help!
