Thank you! After putting all the hard work into it you deserve the images to be seen. I had no idea I could alter HTML files myself, but what I did was opening the file with my Editor program and replacing the image path mentioned above including the img src quot part before that (after some online research) by
img src="Images\
I have no idea whether that has destroyed something, but for the beginning of the game it seems to work and I can see the images now.
