I'll preface this by saying that I know doodly-squat about Jewish ceremonies, but I think the best way to honor the deceased at weddings is with a small remembrance that you carry on your person. I am also okay with the idea of including family wedding photos on the gift table (including those of the deceased and living), but some people are not even comfortable with that.
I would ask your living grandparents and your parents how they would feel about these kinds of touches. This is a really personal, sensitive topic and the answer will differ from family to family.
You can make mention of it in your program or do something personal like carrying their photos with you but I would advise against anything public like a memorial candle, empty chairs, roses etc because it puts a sadness on a happy event and could make some people very sad.
Talk to your officiant, but Jewish weddings don't generally mention the deceased.
It is completely acceptable, reasonable, and beautiful to mention them in wedding programs, to carry or wear something associated with them, and to provide food, drink, decorations, and entertainment that they would have enjoyed.
But no photos on empty chairs, because that can be too morbid, especially for those who have to sit near them. Jewish "memorials," by the way, do not involve flowers.
That empty chair thing would freak me out. I agree with pps, I think something subtle and personal is the best way to go. I'm sorry about your grandparents, by the way.
We have the names in the programs and our officiant is also going to read the names. For the record we are having a non religious ceremony. I think whatever u choose to do, subtlety is best.
