OK, not bad, now imagine how long it would take to load the page if you had 10 photos of that size on your website. 35MB. On a slow speed connection, that could be 60 seconds!
You have to remember two things:
Visitors wait around for around 8 seconds for your website to appeal to them - you've already gone over your time.
Google hates slow websites - pop along to Webmaster Tools to see how it reacts to slow loading sites.

So, what do we do?

Well, thanks for asking.
The answer is that you have to reduce the size of the photos before you upload them.
"Oh, no." you cry, "I'm a prima donna photographer, I can't accept low quality."
Well, don't worry, Norman, it's not that bad and here's why:

A reasonable sized desktop screen today might be around 23" from one corner to another and, in that space, there are 1920 dots of light in rows from left to right and 1080 dots of light in columns down the page. Each dot of light, OK let's call them pixels, is, effectively, a single colour.
If you want your photo to absolutely cover the screen of your monitor, then, no matter what you do, your photo can only be shown with that number of pixels.
There's more.
It is highly likely that your photo will not take up the entire screen. In fact, it might just take up the middle bit of the website so it needn't be bigger that 960 pixels from left to right.
There's even more.
On tablets and phones - the screens are even smaller so when a hotshot web designer like me :) builds a website, we put lower size and quality images on these devices. Let's face it, there's no point having a 200KB image loading on your Android, especially if the signal is crap. That's when your internet speed really makes a difference.
Finally, whenever you resave a photo you suffer some degree of loss of quality, this is due to the fact that a large image might have 10MB of information while as small image will only have 200KB. The process by which this takes place involves some degree of compromise as pixels are effectively lost. This is normally completely unnoticeable, but it is inevitable as part of the process of reduction.

1. Reduce the size of your photo.

Open it in Photoshop or any cheap and cheerful image program and reduce the photo down to the approximate width of the final size of the photo. In other words if your website area is 1000 pixels and the photo takes up one third the width, then reduce the photo to 330 pixels. You don't have to be exact - what's a few pixels between friends.

While you are at it, check out the Resolution above. Over the last few years most creative types will tell you that there's no point creating a resolution of more than 72 pixels per inch. This is not strictly true. Modern monitors can cope with a higher number than this. BUT, my advice is don't bother going higher than this unless you have a specific reason to do so.

2. Change the 'quality' of your photo.

If we take it that the two most common formats for websites are JPG and PNG, lets discuss the ways we can reduce the photo size without reducing quality.
