We were discussing here how screen resolution can be verry important when someone view your pictures on theyr monitor, and since there are lots of people that still uses 800X600 (38% someone said) there is no way they are gonna see your entire picture if it is a portrait and you use the full 640px allowed.
Last night I found an interesting sollution to this on a russian forum (www.photoforum.ru) where they have above every picture 3 buttons. 100% 75% and 50% buttons that resize the pictures same way thumbs are made here. I know php and I know it is a fairly easy thing too do. Wouldn't it be great if dpc would implement such a thing?

It might be useful, but server-genrated images aren't normally very good quality compared to the images saved in PS. You only have to look at some of the thumbnails already on DPC to see the bad compression and how un-sharp they are. It effects some images worse than others, so I don't really think it would be fair.

Windows users could always hit the f11 button in their browser to make it full screen.

Other issue is that: When browser resizes the image it´s not compensated very well. No anti-aliassing is the most commom issue. But colors and sharpness are loosed too. If you use 800x600 you need to scroll. But it´s not too bad. You can view de details to judge as the same way of viewing full image.

I don't know about your php knowledge but when generating images through php there is a property wich referes to quality, values 1 to 10. I been using it, and if used with 10 its like uncompressed and quality is preety much ok. GoodEnd has a point it's resizing without antialiasing that may cause some quality loss. But then again what I'm saying is that by default the normal PS saved file to come up, but users with smaller resolution to have this option. For them it's maybe better a bit quality loss then seeing a scrollable half image.
That would probably be good for everyone. For them because they will have the chance to see an entire pic, and for us because they might vote :)

| How about a photographer's option to upload more than one size choice of the same image for those either on dialup or small monitor res? |

That is an option too, and it's allso easy to detect resolution in php, and show the viewer the picture adequate for his settings.

JPEGs use compression, even at such a quality setting. At such a setting, you often get no visible gains, but your file size goes through the roof. 10 is almost always a bad choice and 9 is not that far behind.
Regenerating an image at any size means that voters do not all vote on the same image. There are already enough variables on the client side of things to be introducing yet another one. Introducing another layer of JPEG compression means you cannot guarantee the output is the same as the submission nor predict how close it will be.
This can only ever be done reliably by allowing multiple submissions in different sizes and you can imagine how hairy that might get. Mind you, only the largest version need only be kept after voting is over, so it might not be such a big deal. Still, everyone would have to worry about generating two or more submissions and I seriously doubt many are willing to do that.
