Best man speech - sharing pictures

Yes seen it many times - nobody prints loads to hand out. The best thing to do is just print up one and have it enlarged and mounted on card that way its big enough so everyone can see it as you hold it up during that moment in your speech then it can be placed somewhere afterwards so the people who did not have their glasses on can go up to it and see it.

longest side about 24 inch will be perfect.

I understand you have loads of ones but pick the best ones for your story and maybe just put the rest in a little flip album and that will get passed around later that way they are all in one place.
