Maximum length of Image Description

[Aisne]

I used to have Coppermine on a previous website and am very much interested in having it again, however the image description area would be very important for what I want to use it for. Is there a maximum limit for the length of the description. I would prefer to have no limit as some descriptions will be short while others will be very long.

The description (caption) can be up to 65,535 characters (utf8).
