Gimp, script that iterates through several images and exports each one with different options

Question

I'm quite new to gimp. Assuming I have N images I was wondering if it is possible do the following:

For i = 1...N
  For each export options j = 1 .. N
      Export(img[i],option[j]);

Basically what I'm doing manually is to load an image and export it using the following dialog:

where (for example) I set different compressions level at each export, or changing 8bpc RGBA to (for example) 16bpc RGB etc.

Also I'd like to repeat the same iteration but maybe for jpeg for example, with other options etc.

Is there a way to script the whole process over a set of say 100 images?
