How to get html address of image in library?

I'm trying to use an api script to set an avatar image. In the api help it says, " You must use an image file that has been uploaded to your Roll20 Library " and "You can view an image's source URL using the developer tools of your browser." But I dont know how to do this, and google isn't helping me find out.  Normally when i want to inspect an element on a web page, i rightclick the element and select "Inspect", but roll20 has its own right click menu and that option is not available to me.  Can someone give a step by step guide how to do it?

You can place the image on the tabletop and press z to zoom it in. In this form, the normal right-click menu is available.

Here's a little test script I use to grab the image source this this macro:  !getImageSrc @{target|token_id} on("chat:message", function(msg) { // use with !getImageSrc @{target|token_id}   //This allows players to enter !sr <number> to roll a number of d6 dice with a target of 4.   if(msg.type == "api" && msg.content.indexOf("!getImageSrc") !== -1) {     var argsFromUser, targetID, targetToken, targetImgSrc;     argsFromUser = msg.content.split(/ +/);     if (argsFromUser.length > 1) {         targetID = argsFromUser[1];     targetToken = getObj('graphic',targetID);     log("targetToken: " + targetToken);         targetImgSrc = targetToken.get("imgsrc");         log("targetImgSrc: " + targetImgSrc);                  sendChat(msg.who, " " + argsFromUser);         sendChat(msg.who, " " + targetImgSrc);              }  else {         sendChat(msg.who, "didn't see any arguments: " + argsFromUser);     }   } else if(msg.type == "api" && msg.content.indexOf("!getTime") !== -1) {         getTime();   }      });

Plex..... might be worth turning it into a "thumb" since API will require that.

I didnt know that, Jakob. Great. Plexsoup, thanks for the script. I'd already found The Aaron had done a script to do the same thing here:  image address script . I like that your version doesn't require to select an image first. 

Stephen actually asked this question last week:&nbsp; <a href="https://app.roll20.net/forum/post/4548528/any-scri" rel="nofollow">https://app.roll20.net/forum/post/4548528/any-scri</a>... I posted a script I wrote there for such.&nbsp;

Haha, The Aaron, my post just before yours refers to that exact script. In my recent browsing of the api scripts form, i have noticed just how many fantastic contributions you have made. You are a great asset to the community.&nbsp;

The Aaron is massively prolific! Also, super helpful and quick to respond.

I'd be more prolific if I could get a few hours to work on things. :)
