I have that one and it is great for making pics smaller but have not had much sucess enlarging. I will be more specific, if I save a pic from the net then I want to use it on my site, it seems to come out tiny and when I drag it bigger I lose resolution, that is what I need a solution for. thanks jg123
Check out the AutoImager image resizer feature. Actually, resample is probably what you want to use. It will give you better quality results. It's not free, but I’d bet you could snag a free copy in exchange for one of your permanent links.
IrfanView uses the lanczos algorithm which produces good results. Another way to do it is stair interpolation, what you do is upsizing the image little by little, for example instead of upsizing it 200% you upsize it 110% at a time. That way you have better results. You can use a photoshop action to automate the process. Hope that makes sense.
This one is free and has various algorithyms to use for enlarging and shrinking images. http://www.fookes.com/ezthumbs/
