I need to use a photo similar to the one in this:

http://bighugelabs.com/onblack.php?id=3518630034&size=large

link as a a background. the page will not scroll down but it will be about 1000px wide. Ive tried enlarging it to that size but the file is then to big. How should I do it without creating a humongous file size?

if you optimize at around 50$ the file size will be about 175 kb without to much loss, it a trade off i would say

Sorry I dont understand the answer :s

What is the 50$ and how would I optimize it?

he means 50% not 50 dollars. Photoshop doesn't save into dollars.

Open in Photoshop or similar image editor and choose file save for web then choose your quality setting. For me 50% is usually too low but on the image you linked to you'd probably get away with it as its so dark in fact you may be able to go lower.

At 50% quality that image weighs in at 147kb which isn't bad at all and it looks fine due to the nature of the photograph.

GIMP also has a save for web function as a free alternate if you dont have those programs

One of my coworkers showed me last week the magic border between 50 and 51%. Both filesize and quality makes a jump there if savings JPG's.

The amount of compression you need depends on a number of things including:


The image

How you are using it

How picky you (or the client) are


For a smaller image, I wouldn't worry about it. For a large, background image I would try various compression setting and go with the most compression that still gives me an image I can live with.

also as it's a background image a *small* amount of blur or smoothing will help lower the file size a little
