Hi, Today I was an introduction to Pharo. As usual, I asked the learner to taste the environment and syntax by running the examples in excellent Sven's Elegant Code[1] (BTW, can I translate snips of it to Spanish?). When she was adapting the example 6 about converting JPGs to PNGs, we get the error reported in this mail's subject. I tried running her example in my machine with her images and with my own and still I got the same error. What are we missing?
