GIMP Photo Formatting Help

I’m preparing my autobiography in GIMP and keep tripping over two hurdles: getting photos aligned neatly on the page and then locking grouped images together so they don’t shuffle when text moves. I’d like an experienced GIMP user to sit with me at my home in Bicton, walk me through the exact steps, and make sure I understand how to repeat them myself.
While in-person guidance is my clear preference, I can consider a brief follow-up via screen sharing if we run out of time. Payment will be in cash at the end of the session.
Deliverable: a hands-on tutorial and a few corrected example pages so I can move forward confidently on the rest of the book.
