I have had this problem before and checked how it was fixed. The solution did not work this time so now I am stumped.
I have a site with 2 master templates and a total of 39 child pages. One of the templates was actually created from the first master template. I have an image that I change on a pretty regular basis on the master template file. I change the image, click save and put all the files. It updates all 39 files (including the second master template titled mastertemplate3). I view the pages in DW and the image is changed. When I view the webpage on IE or Firefox, the image is NOT changed. I have tried syncronizing the pages and that is not working. I am totally confused why all of a sudden my image will not upload.
Does anyone have any suggestions?
BTW - the image is NOT in an editable region so that is not the problem.
