I find a lot good quality images online. But most of them turn out to have a lower resolution than my monitor. It would be great if there was a website or tool that deals with the resolution.
Tony, picture and your monitor must not have identical or similar resolution... how
clear or "sharp" you will see the picture (on monitor) mainly depends on size
(dimensions) of the pic. If you view small pictures on large screen, then of course the quality will be low. There is a nice freeware program where you can change resolution of any picture, so download Irfan View at http://www.irfanview.net/. When you open a
picture in IrfanView, under "Image" menu you should click "Resize/Resample" and
new window gives you possibility for change of several parameters - and one of them
is resolution or DPI. If you increase DPI, actual dimensions of picture will change
and it will become smaller and v.v.
It's not free, but Adobe Flash CS4 will enlarge and interpolate an image to increase resolution, using the transform tool.
There is no way to create information. You can use a service like: http://tineye.com to search for similar looking images of higher resolutions.
You could use tineye.com and see if you could find a higher resolution image elsewhere.
Have a look at SmillaEnlarger
But as Oron says you wont get back missing detail
Tony, it's not entirely clear what you are asking for. You can set the picture to 'stretch' to the entire screen (it's one of the options in the desktop settings window), but scaling an image up will reduce its quality. There ARE programs that do a really good job at enlarging images (see http://www.computingunleashed.com/enlarge-images-without-loosing-quality.html for some suggestions), but even they won't add the missing details to the pictures.
