How to Optimize Your Photos for Myspace/Facebook

people still use myspace...

Facebook's size is 720 px at it's longest side. That's 20 extra pixels.

Jack, the idea is that YOU do the crippling compression, rather than have Facebook/MySpaces JPG processor do it with worse results. Space, in this case, has nothing to do with it.

I have been doing this, but forgot about he 72 DPI thing. good info!

I've just let Facebook resize the pictures and haven't had much of a problem. Doesn't degrade the quality very much at all...They're all sharpened and PP'd enough that the small amount of compression Facebook uses is somewhat irrelevant. We're not using Facebook for professional uses anyway, are we?

Thanks for the info on the OP, it has helped much!

FACT, the old size was 604 or something dumb, but now it's been bumped up to 720.

... but am I correct in thinking DPI has no effect whatsoever ?

Not necessarily. Added DPI means larger file size. Larger file size means Facebook/Myspace will apply greater compression to it in order to decrease the file size to a reasonable size on their servers. This means that, when you could've just decreased the size yourself using Photoshop's clearly superior compression mechanism, you allow Facebook to do it.

Some people use it as a marketing tool. I for one have gotten several jobs via Facebook. It is especially useful when you are mainly marketing to a younger audience.

How does DPI change the file size on a picture where you've manually defined how many pixels are involved?

On an image with a fixed amount of pixels, changing the DPI setting would alter the print size, but the file size would be unchanged.

100% correct.
