I will be glad to help and will copy edit those articles in due course. With regard to the inclusion of Sayedani Maa Tomb - I'm not contesting the merit of the structure. I agree that it is a heritage stucture of significance. So is All Saint Church, Trimulgherry. This church has even recived the INTACH award from the erstwhile HUDA and ASI. Why then am I not insisting on including the following pictures in the article?

If you are insist on including a picture that you think is of real importance to the article, I will also insist on adding the above two pictures which I believe are of great importance as well. The point I am trying to make is that the article Secunderabad discusses several aspects of Secunderabad and not just architecture. The number of pictures in each section should be proportionate to the length of that section. We have enough pictures for the section on architecture. A mention and description of important structures should suffice.
As for the other pictures you have pointed out. I beleive the picture of Garden restaurant has nothing to do with advertisement. The restaurant is a local landmark and is therefore of significance. Pictures of locally famous restaurants are often featured in wikipedia articles about cities. Refer Cafe du Monde picture in New Orleans. The Tankbund road picture is also significant. It is an important thoroughfare in the city which acts as the main arterial road that connects the cities of Hyderabad and Secunderaabd. As for the Parade Grounds picture, I'm not contesting its significance or insignificance. However it doesn't hurt to keep the picture. I hope I cleared things up a bit. Thanks
