I totally agree. but in this case, I believe the goal is to get an image for publication (which seems to be subjective, since I have seen some pretty bad images with terrible resolution in some nice journals). For me, I prefer to make images at the highest quality that I ever think i will ever need (in real world situations). This way, if I ever need the image for something else, I don't have to remake the image at a higher resolution. It is just a waste of time. I think it is better to have an image that is 'too good' than an image that is 'just not good enough.' Sure, you can have the perfect image, that is the perfect size and the perfect resolution, but I believe this eliminates the flexibility of ever using this image for other things, especially if the image is too small. Plus, with todays PC power, it is just as simple and painless to make the higher resolution image to begin with, which you can then edit as you like in your favorite image editing software. Same world, just different view.

That really depends what you want to do !!! For a PowerPoint presentation its utterly pointless to save anything to more than about 640x480, you need even less if the image is planned to be a small portion of the slide. I have often rendered 120x80 images and they look great, since thats as many pixels that the projector can spare for that size of an image in my presentation. Do organize sizes in advance, don't go messing about making images smaller and bigger in PP, you just make quality worse. If you want now a picture for an A0 poster for your next meeting, to dominate in about 40x30 cm (about 16x12 inches), and you will print that at the expensive new institute printer that does 300dpi, to achieve the desired quality you need about 4800x3600 pixels !!! btw, all presentation programs these days accept PNG - its a nice format and no real need to make JPEGs. JPEGs are really good for your camera, but at least in a few cases JPEG compression is not good for molecular graphics. > The bond radius in stick representations can be changed by typing "set > stick_radius = [VALUE]" or "set stick_radius = 0.8" for example.
