70% opacity file: how do I save for the web

[npqster]

I am creating a background for a web image that is straightforward: 70% opacity rectangle. It can't be 100% opaque

I tried the 'Save for Web' option and saving into a .jpg and .gif format and it's making the image loose this key 70% opacity. What's a way to save this?

Is your intention for the image to be transparent enough to show a color or image behind it or just to fade the image down?

Save for web&devices.... png-24.... make sure the transparency box is checked.....

It may save as a huge file....

fade it down

Flatten the image after you do your layer opacity adjustment and save either thru normal save as or save for web..... you'll be ok.

Save the image as a .PNG file with the Interlaced option checked(make sure the background layer is disabled) and you'll have no problems
