Image resizing within the CMS?

[Cerulean]

Uploading images right from photocamera is a bad approach, as they should be firstly resized/compressed manually by editor or a person responsible for media files.

Yojoe, I entirely agree, but in the real world we have to accommodate non-technical clients who don't know what image resolution is. This is especially true when you are serving the small business market, as both I and the GS team do.

Resizing img isn't a main feature of CMS systems.

This is also true, but as a web designer I think that's a shortcoming. A Content Management System exists to do just that - manage content. That content can be text, images, videos, or anything else that people want to put on the web these days. Having an WYSIWYG editor that can insert images is great, but if those images are oversized files that are just scaled down then there's room for improvement. If genuinely resized images could be generated based on the dimensions entered into the WYSIWYG don't you think that would be more intuitive and an advantage for users?

But your suggestion of using the auto-generated thumbnail is a good one, and will be all that's needed many cases. I'm really impressed with GS overall, and I'm looking forward to using it for client sites in the future.
