Hi Riccardo,
Yes, you can customise the name using the `catalogue:imageName` parameter on your interactive outputs, as in the screenshot below :
Note though that Catalogue images use Gaffer's standard mechanism for avoiding duplicate names by using a numeric suffix, and this doesn't play well with having the frame number at the end. In my example I've used `frame_####_image1` so that if you do two renders from the same frame, you end up with `frame_1001_image1` and `frame_1001_image2`.
Hope that helps...
Cheers...
John
