I am working on modifying the TrackerJacker script to add a lot of capability. I am also changing the name and the icon. The problem with working with somebody elses code is trying to change something that you are not sure how they did it. The code has two images hardcoded into the script file feedbackImg: '<a href="https://s3.amazonaws.com/files.d20.io/images/11514664/jfQMTRqrT75QfmaD98BQMQ/thumb.png?1439491849" rel="nofollow">https://s3.amazonaws.com/files.d20.io/images/11514664/jfQMTRqrT75QfmaD98BQMQ/thumb.png?1439491849</a>',
trackerImg: '<a href="https://s3.amazonaws.com/files.d20.io/images/11920268/i0nMbVlxQLNMiO12gW9h3g/thumb.png?1440939062" rel="nofollow">https://s3.amazonaws.com/files.d20.io/images/11920268/i0nMbVlxQLNMiO12gW9h3g/thumb.png?1440939062</a>',
Now when I loaded the script it just worked, even though my understanding is that the developer of TrackerJacker no longer has a roll20 account, the images are still loaded and available. Not sure why. Now I saw the place in API:Objects where it says You must use an image file that has been uploaded to your Roll20 Library -- not an external site (such as Imgur), and not the Roll20 Marketplace. It will begin with '<a href="https://s3.amazonaws.com/files.d20.io/images/" rel="nofollow">https://s3.amazonaws.com/files.d20.io/images/</a>' for images uploaded to the Main server, So I loaded the icon I want as a token, looked at the imgsrc, changed the med.png to a thumb.png, and it seems to be working. Is that the recommended way? If I delete the token the image was made from, and I distribute the script so many people are using it, can everybody use this image and can I be confident it will remain available more or less forever? Thanks
