newbie question:)

well i am all new to this images editing photoshop and everything .
my question is really simple i think
if i got a photo of size for example 110X80
how can i make it bigger for example 300X300
with loosing any quality
thanx!

not possible, sorry. :|

will it work the other way around ?larger pic make it smaller and again good quality remains..

Reducing is usually OK....but one thing you wrote above has me concerned.

That is: the discrepancy between the height:width ratios of your before (and proposed) after sizes in your example. No matter what, the ratio should remain the same, unless you purposely want your image to look squashed or stretched.

Utopian23 yeah you are right about that i chose the numbers randmoly just for the example, to explain what i meant.

There is a plugin called Genuine Fractals PrintPro. This was specifically made to enlarge smaller images. Now it is physically impossible to enlargen an image and keep the quailty the same, but this can do a near perfect job, within reason of course. From personal experience with this plugin, I would recomend it to anyone. It does a tremendous job.
