Hi, I need help with this code. I am trying to display images. My images are in the data folder and are fed in through a images.txt file. The file looks something like this:
DSC01.png
DSC01-mosaic.png
DSC03135.png
DSC03135-mosaic.png
My goal is to have the images fade from DSC01 to the mosaic version and then zoom into the mosaic version and then slowly fade to the DSC03135 and then fade to the mosaic version of that and then fade to the next image or back to the beginning. I want it to be really seamless but I am struggling to get there. please can someone help me with this. I have it so the mosaic is always the second image therefore it will only zoom on every second image.
