@egyptiantraveller I think many people who are senior forum users have been very kindly giving up their time to help others - and this topic comes up fairly often so I understand why they refer back to the checklist.
I think I understand what you are asking - and that is what other people might have done, that worked. When my husband and I were preparing the documents, we asked our lawyer, and they gave us a more detailed checklist. As other users mentioned, the immigration officers are very busy so they are asking for less.
Here is what we did: we created a powerpoint slide and squeezed 40 photos onto 20 pages (back and front) and colour printed them. We also included a text box with all the names, places, and people in the photo.
Hope this helps!
Again seems wasting your time, if they wanted more than 20 they would ask for them. 20 is more than enough to show evidence of a relationship. The main thing is to try have photos that show the evolution of a relationship, they don’t want to see all photos that are just selfies of the 2 of you, quality not quantity. For example we sent 3 or 4 from visits when we first met, 4 from our wedding, 7 or 8 from family occasions (Christmas, birthdays, christenings, weddings etc)with other family members in the photos with us, and a few from a vacation together.
