Because so many things are now available in digital format physical magazines are on the decrease. I mean why bother buying written material when you can have it available online? You will likely throw away the physical magazine after a few days or weeks anyway once it has been read.
There is one good reason for having a magazine in your house though. Once your child has read through the pages they will never be bored in going through them over and over again, pointing to the animal or object and trying to mutter some sound. Hopefully, after a few blundered attempts, they will be able to come very close or even match the picture with the correct word.
Once your child has turned their attention to something else you can still cut out the images and use them for other purposes, for example on a scrapbook. You could also teach your child to stick the pictures themselves, using some normal harmless glue such as a UHU stick. What’s better you can only allow your child to do this once they have pronounced the word correctly. The glueing part will be the just reward for your child’s accomplishment!>
