I think that the only way to do that is by asking the position of the cursor all the time, resulting in lots of lag.

You can do it by using any timer hook ( cs2d lua hook

ms100,

second, etc) to call the cs2d lua cmd

reqcld function (in mode 0), which calls the cs2d lua hook

clientdata's hook function. So, in the cs2d lua hook

clientdata function you will have to ask where the cursor is, and if it's at the image's position, then you swap images. Then you would want to ask for when the cursor leaves the image so you change it back to the original.

I think it's not worth doing such thing. The only way I think it wouldn't lag is if you use the cs2d lua hook

second hook, though it may look very unresponsive.

You can use this post's responses as reference as how to do this: LINK
It's basically the same thing.

Serigala's code works but on the 23 line it triggers an error due of an unfinished string. It can be fixed very easily by just removing the unnecessary quote.

Probably won't work as expected.
