Jup I Read the guidelines, the ones you have posted are the ones of Usage of there site :) there is a big difference. I cant Imagine that Disney, Lucas Warner etc would be using it if they could take there rights :) Or you just had a Look at the Android app and online Image creation guidelines. but not the Image enlargement filters. It does not matter, You can use the old fashion way others will Improve. Fearing the new does not bring you any further, No Improvement's no sales that is the rule.

All you say gives me rather the Impression of a fear not being able keeping up, at the end you for sure will have to find a good solution if you want to redistribute your works or get a little attention on them, no way around making your works way better. Others will that's for sure :)
