DepressedChimpanzee34 ClearML tries to conserve storage by limiting the history length for debug images (see sdk.metrics.file_history_size https://clear.ml/docs/latest/docs/configs/clearml_conf#sdk-section ), though the history can indeed grow large by setting a large value or using a metric/variant naming scheme to circumvent this limit.

Does your use case call for accessing a specific iteration for all images or when looking at a specific image? Note that the debug image viewer (when you click a debug image) provides an iteration scroll control which allows quickly moving across the entire available iteration range for that image.
