We’ve fixed a bug affecting thumbnail generation on images where zone annotation tools were selected, but no zones were actually drawn. In these cases, HERAW now correctly falls back to the default image thumbnail instead of leaving a broken or empty thumbnail.

This correction ensures that your visuals are always represented with a proper preview, even if annotations were not finalized, preventing confusion or display errors in your media libraries.

With this fix, HERAW reinforces visual consistency and reliability in your annotation workflows, making sure nothing is left unclear.
