Why do photos that were licenced open up small when I put them on adobe premiere?
Do they need extended licence? If I get it will it open up and magnify without distortion or pixilation?
Can you please share the File/ Image IDs which you are facing troubles with?

But to answer your question about the extended license ... no, the licenseing level will not make any difference.
