Image types

can't I have opacity and transparency set in the same image??

[ryanoasis]

When I save as a jpeg I have opacity but not transparency.

When I save as a gif I have transparency but not opacity settings.

Did I miss something? Because I think I remember getting both.

This may not be the place for asking this question but oh well, I need help.

Thanks

I think you have it sorted out properly: JPG is a good file type for photographs and other 100% opaque images with a lot of tonal variation. GIF is a smaller file format for images with flat color (cartoon or illustration style) and for images where you need a transparent area.

PNG is a lesser known file format with native support for alpha transparency, but currently enjoys only partial browser support for it's more advanced features. Check here [webmasterworld.com] for links to more info on PNG... It may be what you're thinking of.
