OK....I give up....would some kind person spell out in simple terms how I can save a good quality jpeg?......Perhaps tell me what render settings to use??

I have tried all manner of settings and haven't got a result yet.

For a quick render of say, a human form, the render takes say 25 seconds max....From this I can save a jpeg of usually 55kb to at best 112kb (the larger file occurs when I 'crop' / close-up the view)

With settings for a longer render.....Ha Ha (3hours 23mins) I got an error message 'render failed to save'.

I have tried saving 'Scene', 'Last Render', to another window (always fails).

Just how can I get the complete image saved at say, 1.0Mb?

Thanks Al
