Topic: Picture sizes

Hi General question for everyone.

What do people generally use as settings for size and resolution of the pictures they upload?

I want to try and find a happy medium between the quality of the pictures and file size for uploading, and also the size it then displays in tiltviewer when you zoom into it.

Do you generally use photoshop/lightroom, to resize/change resolution or keep them as they are and use svmanager rezize function?
