I usually do my image editing in native apps like Pixelmator, Graphic and Preview for Mac. However, I thought I would try Sumopaint to crop and do some basic editing, like removing text, since students would have access to it when doing an assessment that requires editing images.

Through this activity, I also saw how limited the selection was for images of Mathematical diagrams on Creative Commons and on Flickr’s Creative Commons licensed photo selection. I had more success doing some searching in Wikimedia Commons but often the image is not exactly what I’m looking for. I hope to learn how to become better at creating my own images through this course.
I agree Kaz, there really is a limited number of math images that are copyright free. I often I have to make my own which can be so time consuming.
