The colours are a bit different thats all, and thats because I always set the colour profile to sRGB, the origonal pic was adobeRGB and I couldn't be bothered altering the saturation to allow for the difference, there are no jpeg artifacts showing in my copy and that is what I meant by quality.
But if you all want to have <500KB 800x600 pics to look at thats up to you, for me I am starting to avoid threads with screen shots in them.
I belong to a photography forum where quality counts and most of them are around 200KB (800x600) and if you post images over a meg you get warned to stop, if you don't stop, your out.
