I have today used publisher for the very first time and felt rather proud of the poster I had created, then when I tried to email this poster to someone the problems started, I ran it through design checker and think the solution would be to make the poster smaller (as the pictures are coming up as low resolution) I have tried the way of going to page settings and reducing the size but still the same, I don't want to do this poster all over again as it took ages to do, but I am losing the will to live at the moment Any suggestions please? be aware I am not very technically minded!!I created the original poster in publisher 2007 and have updated my version of publisher, there is an option for me to put a file onto publisher but when I try and do this it says it's already on publisher!!

If the recipient of the poster via email doesn't actually need the file to be in a Publisher format (to be opened in their version of Publisher), have you considered printing the PUB file poster to PDF via the printer selection menu?



Windows 10 has this PDF print option available or your newer version of Publisher may have an option to Export (File > Export > Create PDF) the poster as a PDF.
Then it's a simple case of emailing the PDF poster for the recipient to view.
