 # Notes on ImageMapster.js
 
-The original creator's [repo](https://github.com/jamietre/ImageMapster) is no longer being maintained. Several forks exist, but they also see minimal commit frequency. The current local minified `imagemapster.js` is based on [this fork](https://github.com/davintoo/ImageMapster), specifically, [this commit](https://github.com/davintoo/ImageMapster/commit/47145f22cabb8ac3a415da3e5843fd204bb0abca) from another user who has not been active since March 2018.
+The original creator's [repo](https://github.com/jamietre/ImageMapster) has a JavaScript eval() in the [imageMapster.js](https://github.com/jamietre/ImageMapster/blob/main/dist/jquery.imagemapster.js) in a test code. To remove this, we have followed the following steps:
+
+- Remove the lines that use eval() in the [imageMapster.js](https://github.com/jamietre/ImageMapster/blob/2e6f0eaf9093b4407dffb84ef8bebf0769802d38/dist/jquery.imagemapster.js#L1325-L1327).
+- Used an [online tool](https://www.toptal.com/developers/javascript-minifier) to minify the code.
