Setting slider value as sprite scale?

I'm using a slider to scale images/sprites, so when I click on an other image, I want the slider to take the image's scale and set it as it's value.

I can set the scale to the slider's value, but not the other way around, as seen here: gyazo.com/f51712a394eae713e64b731adb1b7490

How could I make this happen?

Should work fine. You probably have a picking issue.

You might be right. When I pick an other image, well let me show you instead...

My english isn't great, so I'm better off showing it in video XD

From the manual:

ImageWidth

ImageHeight

The original dimensions of the object (its current animation frame image size), in pixels. Since objects can be stretched at runtime causing the normal Width and Height expressions to return different values, these can be used to get the original size regardless of the stretched size.

Its a matter of approach.

perhaps, give the Templates a variable, "SelectedScale" (number)

When sliding the slider scale, set the value of the Templates.SelectedScale, followed by setting that value in the Templates scale propperties.

When selected the image to edit, grab their SelectedScale and set in the slider.

Awesome, thank you for your input. Will try this.
