Hi all,

What are the ideal settings for displaying images on the web?

I am limiting my images to longest width of 800px but should I save them as JPEG maximum (12) , JPEG high (10)... does reducing the quality to 10 make a difference on the web?

I am also limited my resolution to 72dpi, is this correct?

Cheers,

if you use the save for web function
at jpeg 61 compression that is pretty optimised for the web

jpeg 10 in 'save' as jpeg is high quality is quite a large file compared to save for the web

thanks Wendell,

I was hoping to export from Aperture as a JPEG and not use Photoshop, I think Aperture only has ratings, rather than save for web feature.

Do you know what the equivalent of 61 compression in Aperture is?

Cheers.

hi woody

i dont know i as i dont use aperture

i guess anything that sounds slightly higher than medium would suffice like

60 -70%

what image size is ideal?

In Aperture using quality setting 8 and limiting to longest side 800 px I get an image size of 228kb.

Sounds ok to me but if I have 30 - 40 images in one flash slideshow is that to big?

Sorry for all the questions

best way to export a couple of jpegs using different settings, zoom in on each image and try to determine the threshold where you get to see jpeg artifacts large blocks you cant live with then you

you will notice images with reds are more suseptable to jpeg artefacts
so if an image has a lot of red tones in it you may need to save it at a higher quality compression rate to compensate

228kb for 1 jpeg image at 800 pixels on the widest side is pretty big

aim for 90 to 120kb

mind you in press i used to submit images at 3000 pixels on the largest side 300dpi with a jpeg compression of 9 and i got image file sizes around 900kb
that was good enough for press
