Hi there Littleus,

I am not an expert on the matter but it shouldn't render it transparent automatically. You have the option to make it or parts of it transparent it seems.
There is a great article on .png images here: http://www.libpng.org/pub/png/pngintr... which should give you a lot more info on them and variable transparency. (I am learning new things about .png images just by reading it now)

I hope this helps you.

It allows the background stay transparent .....If I make a banner with text only and a transparent background then choose to save as....If I save as png the background will stay transparent....Save as jpg or bitmap and you get an opaque background.

Hi lu,

A very late entry on this topic:)

png files will allow you to choose a transparent background. There are programs also that allow transparent backgrounds with gif files.

A very intersting aspect of this is using the online Picnic image facility. This will destroy a transparent back ground and simply replace it with an opaque white background. I don't know if there is anything that can be configured in the this module.

Thanks Peter I thought Picnik would not do that.....I just made a simple transparent banner and put it on my backgrounds pages....I will change instructions ...Many other graphics programs will destroy the transparency also....I know Gimp and Photo Shop work...I will give Paint.net a try and see if it works....that is a free and easy program.

Bugger!

I just realised that my statement is unclear,. I meant the image manip module in Yola. I have no idea if the free standing Picnik does it correctly.
