I think by default it looks in the sketch path, not data path. Either move your image up a folder, or use img = loadImage(dataPath("defect_walk0001.png"))

Yes, it works with the absolute path :smile:

Or, yeah, that. Same problem you( @Sky ) encountered in your another question where you struggled with width and height turning null - dataPath and sketchPath also only work in setup() or later.

[image] Architector_4: dataPath() and sketchPath() also only work in setup() or later. Actually anything related to sketchPath already works as soon as settings(). Same for args[]. :nerd_face:

There is a method to know if an image was successfully loaded ? (I’m getting a null ptr error on the 36th frame, but when I print() the loaded files name, it seems all ok)

[image] Sky: There is a method to know if an image was successfully loaded? Nope. We simply check whether loadImage() has returned None. :no_mouth:

Files must be loaded inside setup() or after it has been called
