Sizing

[Gingersnaps]

I will ask, what is the correct way to resize images? for facebook? web? I am also sending off an image to a magazine that has a maximum file size of 5mb. I don't care how silly I sound, I don't know how its done properly and I want to learn.

For Facebook, the optimum size is 2048px on the longest edge (either high or wide).  For other websites, you'd need to investigate to find out their optimum size.  Use the Image Size function.

In this example I'm preparing a photo for Facebook, and it's a portrait (tall) photo, so 2048 is my height:

It's really important to have the "Resample" box checked, and set to "Bicubic (smooth gradients)" as I have done here.

This is a different matter, and it's never easy.

Did they give any other specifications?  About resolution, or colour space, or anything like that?

no, just Jpeg at a maximum size of 5mb. I got it down to 5 by just changing the pixel dimensions on the long side until the image was the required size.

Ehh ... I wouldn't have done it that way.  I would have left all the pixels there, and controlled the size by lowering the Quality Level of the jpeg save.
