Converting .png to .jpg

How the hell do you do it? Can you use gimp to do this? Is gimp tough. They can't view .png in Microsoft, right.

most graphics and editing tools can do this including the gimp.. Also, newer MS browsers should have no problem viewing .pngs

use "convert" the gimp, or a billion trillino other filters. i prefer convert...

convert file.png file.jpg

that's it.

Okay, I didn't know that MS could display .png's.

convert is part of the ImageMagick tools. It's quite handy to have around for mass manipulations and such.

But can convert do mass conversion? I.e. if I have a folder full of PNG's, can I do:

convert *.png *.jpg

or will that b0rk?

You could do something like:
for picture in *.png; do
convert "$file" "${file%png}jpg"
done

If you use KDE and have ImageMagick installed all you have to do is right-click the files in Konqueror, go to the Actions menu | Convert To, and pick the desired format.

They can view png in Microsoft. I am going to assume you mean Internet Explorer.

The problem is alpha channel that doesn't/didn't work so well. But, if your images are not using the alpha channel and yet again I will assume they don't because you are going to jpg, then yeah just use png.

Otherwise you go to gif and use transparency.

The alpha channel helps when you have a image you wish to place on different coloured backgrounds, it is smoother than transparency.
