How to use the images from ImagePicker?

I want to use the uploaded images, like for TextureLoader in three.js:

 _pickImage = async () => {
        try {
            let result = await ImagePicker.launchImageLibraryAsync({
                mediaTypes: ImagePicker.MediaTypeOptions.Images,
                quality: 1,
            });
            if (!result.cancelled) {
               FileSystem.getContentUriAsync(result.uri).then(cUri => {
                    const loader = new TextureLoader();
                     loader.load( cUri, function(texture) {
                        drawPainting(texture);
                    });
               });

            }
            
        } catch (E) {
            console.log(E);
        }
    };
