I'm building a web page in Publisher 2012, the page has a number of photographs which I've created as PNG files. The problem is that when I select web preview, all of the photographs have a black border / surround. I have turned off all the borders but the problem is till there; the normal Publisher document view doesn't have these borders.
One thing I noticed is that all the images in the web page view have been converted to JPEG format; I know that the compression option can do this, but I think I've disabled that option (difficult to tell if I have for certain, but I de-selected all the options then selected compression for all images in the document); that didn't make any difference though.
It appears the border appears during conversion of the images top JPEG; the question is, how do I get Publisher to keep the images as PNG?
