the adhesive (whichever you choose) should not have any effect on the photo. However, apart from the pva i would advise using them either outdoors or with windows open. i spray the paper and then stick onto the canvas. make sure you have the canvas marked in some way to show exactly where you want to put the paper as the best one does not reposition. the others do not move after a fairly short while and of course if moved leave the canvas marked with adhesive.
you can get these sprays from any good arts supplier.
good luck.
