How can I replace all images in the project?

My prototype is 360 x 480.
But I used a really big asset (three times)
… because I do not want it to look blurry on the phone.

This is a mistake.
My prototype is really slow on mobile devices.

Is there a way I can replace every image in the project with a smaller image?

My prototype is way too complicated to do this manually.

Hi ElwoodHernandez,

I’m afraid there isn’t a way to replace every image in the project from a central location, but I’ll go ahead and submit this as a feature request with our respective teams on your behalf. One way to do this dynamically, however, would be to add a Set Image interaction OnPageLoad of each page to target the images on each page to the smaller image. What may also help is to optimize each image by right-clicking on the image and selecting “Optimize Image” (though this will remove any transparency the image had).
