I am currently trying to take an embedded image out of a report's .resx file and point it (relatively) to a file in an images folder in the same project. I have tried every combination of the relative path in both Report designer and even setting it in C# in the report's constructor in the code behind. When I set the pictureBox's value to .\Images\fpi-ontarget-letterhead-black.jpg , it works in design mode, but in preview mode, I get the error: "Invalid URI: The format of the URIcould not be determined." I noticed that if I set an absolute path on my hard drive, it will work, but I would like to avoid that. I would like to get it working with a relative path. Thank you in advance.
