batch scale down images if largest dimension is greater than X

[karaxus]

Hi all,

I am trying to scale down a number of images (~ 100) of different dimensions down to a specific maximum size (for example 1920px as width).

I searched for this but didn't find any plugin or so which allows me to do this.

I tried using Batcher but it's missing an constraint option on image dimensions.

I am not an expert user of gimp, but maybe there is some script-fu (?) I am missing for solving this issue.

Thank you all in advance for your help.
