Sticking photos in an album

This might sound a bit random what's the best way of sticking photographs onto the pages of a photo album? I've noticed a lot of albums these days don't have the cellophane pocket thingmebobs. I'm guessing some kind of glue but does it need to be 'special' glue for photos or anything?

TIA

I use an acid free, double sided tape - much easier than glue.

An example: http://www.handyhippo.co.uk/p537-Double-Sided-Tape-6mm.html (I've never used this place to buy stuff, just an example of what I'm talking about)

A lot of craft places do it.

i use photo corners which are small pieces of acid free double sided tape but alreadu cut so you just put on in each corner and peel of voila.

They sell them in hobbycraft and almost all craft shops.

Just remembered that I use this too: http://www.sirstampalot.co.uk/product_info.php?products_id=24456

It's really easy to use and works great.

Bought it from Sir Stampalot (see link above) - they seem to be a good company

Thanks for the replies. Can't believe I didn't think of double sided tape!
