Whenever I try and upload an image, it does not work.

Somebody reminded me recently that if you resize the image and make the file size smaller, it will work.

I'm wondering if anybody knows what the actual file size is as a maximum that I can upload?

Rather than just wing it, I would like to create a script that will create the appropriate file size.

I don't want to be greedy and use up heaps of resources, but I'd like to find what the happy balance is and make sure it works within the limits of the system.

Thank you so much.
