How does using pictures affect the download time of the site?

Does it depend on the size and quality of the pictures?

Are there any ways round this problem through scripting etc.?

Any help would be great guys :cool:

Pictures can take up much bandwidth and time to load. It all depends on how many you want to load. If the picture is big you can preload the image before the page comes up. Many users still have dial up so always be conscience of them.

There are many ways to compress pictures for the web, Paint shop pro or photoshop is a couple of options. If its pictures, use jpeg for the best quality at small size. For graphics stick with gif images if possible. The load faster. (png is also good) Another idea is to use thumbnail images with link to larger size if that is needed.

You can use PHP script includes, but the page will still load the same. It might be a bit quicker, not sure for certain on the time differences.

I think if you have a huge images with high resolutions I agree, however if you have a small image say 30 by 50 and you stretch it in coding to 50 by 70 you will see a bad picture, revering that and going smaller usually works since the eye cannot pick up on that sort of thing. So image size does affect depending on what you are doing with the image. Since most images are not taken by the person, its hard to get the size and quality issue down.

As a general rule, resize the picture by how you intend to code it in. If your image is 150 by 150, used coding to reflect this site, if you need smaller resize image. That way code adn image size can go hand in hand.

Yes, Term, I'm all in favour of smaller file sizes and faster loading. I included the link because I think it is a good all-round discussion of the size issue, and contributed to a fuller understanding. Also I think that the other content links on the site are very useful.

I've often advised putting thumbnails on the page that loads, where appropriate and feasible, with the option of the user clicking to see a larger version. This way the user has chosen to wait for the image to load, and should therefore be prepared to wait for that to happen. But where the image is essential to the design, it should be optimized to have as little effect on site load times as possible.

We are on the same page here, for sure!
