Ok, what i need is to resize images to be exactly 800x600, but ofcourse when you crop the image, you cant just do a usual rezise cos the ratio wont be right.
So how to resize images like that?

One way to do this is the following:
- Pick the crop tool
- In the upper toolbar, specify the size you want. Do not forget to add the word pixels, otherwise it will pick centimeters.

- Select the area you want
- Press apply.

If you want to resize without having to crop (you just want to shrink what is already there) then go to Image->Image Size and then type the size in the boxes at the top, and hit OK.

If you are only resizing you could also use WinXP Power Tools Image Resizer

also make sure when you are resizing in photoshop that you set the aspect ratio to 800x600. There is an option to set the crop to 800x600 but this will most likely not capture the image you are looking for - setting the aspect to 800x600 will allow you to keep that aspect ratio so that you can crop, then easily resize later.

im not sure if it has been clearly answered. for resizing, just make sure the aspect ratio box is checked and enter your size and press enter:D

The aspect ratio box is actually called the constrain proportions box. Aspect ratio is something else, it refers to the size of the pixels.

Usually pixels are the shape of a square. However, when using an aspect ratio the pixel gets a different shape. You usually don't need to use aspect ratios for pictures unless you create them to use them in a video. Unlike image files, most video files (that is, those that are played on dvd player) do have an aspect ratio. There are for instance different aspect ratios for PAL and NTSC and the different types of widescreen.

By the way, technically you can use aspect ratio when resizing. If you have a picture with dimensions that are 3:2 and you want it to be 800 x 600 and you definetly do not want to crop, you just resize with the "constrain proportions" box unchecked. The image you then get as a result will be distorted. It will be stretched vertically. You can correct that by setting a custom aspect ratio to 1,125 (I calculated this number myself by comparing the proportions of the image before and after the resize). Now you will see the original image, without distortions, but still with 800x600 pixels. Unfortunatly, there are not that many programs that support aspect ratios, the image viewer of windows does not display the aspect ratio, so the image looks distorted.

Actually in this case, Photoshop uses aspect ratio to mean the ratio of the sides of the selection tool. In this case, the rectangular selection tool has been chosen with a fixed aspect ratio of width=800 and height=600.
