Thank you very much for your support! In fact now picture pair is equal - although some may look very similar. Some pictures may loop - but that is because we need to compare some conditions to the same "base" condition (e.g. size asymmetry from a C-Cup breast compared to an A-Cup and a B-Cup breast...so those two pairs are different, but the "base" of a C-Cup appears twice. The study is designed that way so that we are able to cover every important breast condition in one survey. I hope that explanation helps - thank you very much again for your support!
