Enlarging image, what to do after resize?
I have a small imahe lije 100X100px and I need somethinh 500X500px.

After resize you can imagine how that picture look like!

What usualy do you do to make it a little bit beter?

imahe lije = image like ?

ok, i dont think there are much possibilities to increase quality when you are enlarging, since we are talking about a non-vector based format.
you could try to apply the sharpen filter and play around with the enlarging-algorithms.

The picture is jpg format and that is the only source I have, nature and it iis not possible to "remake it in freehend, corel draw etc..."

You're asking a bit much to increase the size of a JPG by a factor of FIVE! and still have it looking OK. It is just not possible. You are trying to create pixels that simply do not exist in the original file. If you retain all the original pixels and increase the size, those pixels are going to be spread so far apart it will look terrible.

I did smart blur, then made chanels for objects... apply some lighting effects and I made something that looks quite nice...

#!/usr/bin/perl 



print "Content-type: text/html\n\n"; 

print "Hello World!";

I'm assuming this will be for web and not for print.
It can be done but it's a royal pain.
Assuming your document is 100x100@72dpi
Double your final docs pic size by increasing the dpi amount. (ie. make your 100x100 docs dpi about 600 dpi, this will give you an image of about 1,000x1,000)
Save the image.
Now the tough part. Remove all the artifacts and little gremlins within the image (clone, hand paint, erase, etc). Once the image is "clean" save again.
Now resize the image to it's appropriate dpi and HxW.

The reason to make it bigger then your final file is that you've more information to work with. The more info to work with, the better off you are. Digital matte painters use this alot to craft the little details that make what they do so realistic. That being said, it does take a lot of time, and is a LARGE pain in the ass. It's easiest to do with simple image. So you really need to ask yourself wish would be better, re-creating the image from scratch or to clean the image?

Good luck
