While trying to update an Excel 2003 Add-In to 2007, I thought I finally had the hang of getting the XML code and inserted. *.PNG Icon image in the MS Office 2007 Custom UI Editor to work in conjunction with the necessary VBA code because I was able to accomplish same with a single instance of this process. So, I continued to add a couple dozen more of these images to my *.xlam file, added the appropriate "image="" parameters to the XML, saved and closed the Editor and then opened the *.xlam file in Excel 2007. However, I am now getting a slew of "An error occurred while loading image with relationship ID ..." errors (with each specifying the name of the embedded icon file) - I believe I am getting one error for each image now in the file. All of the images are *.PNG files. Help is not available in any form.
I appreciate any insights on what I might need to do here.
