Hi everyone, I'm very new to GIMP and photo editing.

For a project that I'm working on, I need to rotate a batch of images (50k+), the good news is that the rotation that I need is constant and Gimp works perfectly for that.

I tried with a single image and everything that I need is to do is to open the .jpg, use the rotation tool with the following options: 0.2°, cubic interpolation and crop with the original image ratio. After that with just another crop around the image borders the process is complete.

Clearly I can't do that for 50k+ images and I need some automated way. I saw that there is the possibility in Gimp to import external tools/scripts or to work via console.

With the premise that I know how to use Python, what do you think is the best way for me? Plug-ins like Bimb only rotate the images for fixed amount of ° and I'm worried that I can't set parameters such as the interpolation. Can I do that via scripts or the options are very basic for them too?

I tried so search on the web for suggestions but the results are old and maybe something new is already available

You can still use BIMP and 'Other GIMP procedure' As the screenshot. Deprecated
procedure but still works. You could write your own script using those rotate
functions.

However 50 thousand images? Is Gimp the correct tool for this. ImageMagick (IM)
is better suited for large batch operations.

Ask the question on the IM forum https://www.imagemagick.org/discourse-server/ In the user section where they are very helpful.

Cool! I'm trying to use Gimp because the rotation tool is already combined with a perfect crop for what I need. I tried with several python modules but then I need to set specifics crop for each image.

I'll try first with Bimp, if it doesn't work I'll give a look to IM
