Clear your browser cache and then load the home page for http://www.classicamiga.com and then tell me you are happy with dial-up!

The internet has moved on Steve. As usual you have been left behind.

He's not been left behind, it's all a big plan so we have to declare him Leader when our backs are up against the wall during the next stone age.

Here is an image that has been sized to 1024x768 with 80% IrfanView quality: http://emaculation.com/steve/monitors.jpg

Here is the same picture, but was saved with 20% IrfanView quality instead: http://emaculation.com/steve/compress.jpg

If they look the same to you, then you either need a better monitor or your eyes testing.

Both look like messy bedrooms to me except the one that's compressed more looks tidier as the crap is blended into one item.

It isn't an exact science Steve! I forgot how literally you take everything ever said! You have to experiment with the levels of compression to balance it between compression and quality. There is no way you could just say 20% for all images as all images are different.

One of the cool things about Photoshop is it's "Save for web" mode where it gives a live preview as you adjust the quality - makes finding the balance pretty easy.

Exactly what I use! Used to be a sort of simplified part of Image Ready, but Adobe have now ditched that in favour of Fireworks. Shame really as I liked Images Ready more for creating web graphics. I find Fireworks a bit too complex and vector based for what I normally need to do. But I'm glad they did keep the save for web mode in Photoshop as I use that the most. A quick Ctrl+Alt+Shift+S shortcut key combination and up it pops.
