This has been the most productive day so far. I figured out the problem with saving the images, so the work I did can be recalled later. The only radio images I have are Hydra and Perseus, so I got the contours done for those clusters. To make the rest of the clusters easier, I made and saved contours for each of the X-ray images. Then I rearranged the folders so that images of the same cluster are in the same place.
