resize to 320x240 with AR ? ?

Specs: Windows Vista
I am having a hard time figuring this out. I have tried paint, irfanview etc but when I am trying to resize a wallpaper that is lets say 800x600 to a size of 320x240 with the aspect ratio checked it never comes out as a 320x240 its always smaller. If you need it exactly 320x240 or 480x320 as the final image size what do you do. IF I shut the "use aspect ratio " off then it will save it to what I need but it will look like crap?

Help me please

Unusual problem in that it shouldn't be a problem. I just tried it myself to try and understand what could be going wrong. I took a 4:3 (800x600 .bmp) aspect ratio picture and opened it in Irfanview, opened the "resize/resample" dialogue, with the "preserve aspect ratio" enabled I simply change the width from 800 to 320 and the length automatically changed to 240. I then saved it as a 320x240 jpeg. Now, I couldn't have changed it to 480x320 because that's a 3:2 aspect ratio (I assume you probably meant 480x360). I'm using Irfanview version 4.10 it doesn't have any problem making the size conversion you are asking about. Maybe there is something peculiar about the particular photo/format your trying to resize? (but, I have no idea what that would be).

I agre with pyrolitic, the 800x600 should convert correctly to 320x240 because they are the same aspect ratio. The aspect ratio is the critical thing. For example a 1280x720 picture will not look right if converted to 320x240.

Figured out my user name:

The problem I am having is this. I was only using 800x600 as an example. Some pictures like this one I just tried when I tried to resize with AR checked I input 320 and it made the height 200. I need it to be 240. I tried to make it 480*320 and I put in 480 and it defaults the height to 300 not 320 :(

Some pictures work fine but for the most part not. I also like to size to 480*320. I am working on wallpapers for my phones this is why I wanted to learn how to do it so if I ever see a pic I want editing it will be a breeze but it never works right.

Appreciate any help. Has to be a way? right

The only way to change the resolution of a picture to one with a different aspect ratio and keep the proportions correct, is to crop (cut off some of the top/bottom or left and right sides) the picture or add letterboxing (black borders on each side or above and below).

Thanks again

Thanks for the bad news, huh. Sorry. :-(
If you have a decent photo editor, cropping the pictures is pretty easy, and you can usually end up with something pretty decent.
