Best way to mount photos into an album?

[gixxer1000]

Hi folks. I've just about managed to finish the rather laborious process of hand printing about 150 photos from my sister's wedding and now need to mount them in an album. What's the best way to mount them for longevity? I was thinking of using spray mount, but am not sure if that will damage the photos.

Any thoughts welcome.

Cheers,
Gixxer.
