I use PhotoFiltre to add text to my images and when I save the in PNG format I am given THESE choices.
Could someone please explain them to me ? :)

they dont really apply here Lyn as the interlacing is for how a PNG loads on a web page. the caedes server converts the PNG to jpeg anyways so that becomes irrelevant. usually, if you have a PNG on a web page you would have no interlacing that would mean the image only displays on the page when the browser downloads all of the data or interlaced that brings in progressive low resolution depictions of the image as it loads - it seems like the file is quicker to load that way but really it isn't. in much the same way when a computer tells you a copy will be finished 'in about a minute' :-)

Thanks Phil, glad I can ignore it as I have been.

Thank you both! I was wondering about the same thing...
