@adsatinder ji.You can post more pics than 10 Pics per post.
10 Pics per post. make page lighter to appear fast.
This is the only purpose.
If you want to post more, you can do maximum 50 pics (limit of forum software) per post also !
Index is of better use as it takes to the desired point.
My next travelogue will not be with INDEX, and I will post 10 pics per updates.
So that page will appear fast.
