Resize uploaded image on specific directory and security aspects

[danjde]

Hi Devs,
I would like to auto-resize every images uploaded into specific NC directory "Test".
I've been seen more than one way on NC forum, and often some of these examples don't seem to consider the security aspect of this operation.

If possible, please could you show a secure and working example related to this case?

Many thanks!

Probably not the place here, but rather in the forum (in which case a link would serve):

What are the examples you found and what are the individual security concerns you have?

Maybe you could create a collection pointing out, what needs to be addressed.
