Something like this, I found this on a example business presentation, and for my assignment I would like to create the same effect in gimp, making transparent jagged-edges for likely a image on the right, to look better blended with the slide on the left, how would I do that in gimp? I tried setting a alpha channel, and erasing parts of the image, but it only saved a small portion of the image as a png, and just look severely distorted as a jpeg. (Original image was webp, and I selected the option to fit the canvas over the layers). So if you have a idea on how to approach this (preferably a step-by-step guide), I would like to hear it

Do you have Inkscape installed? I think it would be easier to draw the mask, i.e. the edgy edges, in there. You could just trace the one from your example pic as well. And then you could go back to GIMP and attempt the same procedure again. I would just make sure you convert all your images to PNG or JPEG. And to make sure you add the alpha channel before you do anything else.
Tbh I would use the clip function in Inkscape and then export the image as PNG to use in your slide. But I've always been more comfortable on the vector side of things.
