To mount the photograph onto your mounting board or portfolio sleeves, you can use 3M 75 adhesive which is repositionable but permanent after drying. It becomes tacky in 15-20 seconds, and it has a drying/bonding time of 3-30 minutes.
It is a commercial alternative to Spraymount, and you get 25% more adhesive for a lower initial cost, i.e., 500ml.
