can you store flickr images from the php api to your own mysql table, or is the server only temporary and farm id etc, will they change over time?
I am trying to make a simple pinterest type of script which I will store the image url to a mysql table and link through to them directly on my website.
is this possible or do they need to be saved.
As per OP's request:
You'd be best saving the image on your own server then, if you're concerned about them potentially changing the URL.
Don't save it as a blob in DB, but physically on your server. Doing a blob will dramatically increase the size of your DB over time.
