Adding pictures to sheetformats

Hi,

I'm having an issue with Solidworks 2014. I'm setting up drawing templates and wish to include a company logo as either an jpeg or bmp in the sheet format.  

I had no problems inserting, resizing and placing  the image, however when it came to saving the sheet format it came up with the error 'An unknown error occured whilst accessing C:\....... '

For a while I couldnt find the cause of the problem , however I removed the picture and it saved, re added and it wouldn't so I think I've found the problem!  Question is, can anyone explain the problem and or provide me with a resloution/work around?

Many thanks

Alex
