Have you tried uploading to Qualtrics as a file instead of an image?

No. Where do I do that? I don't see any link to upload to my file library. I see a survey, graphics, and messages library. I also can't seem to upload it directly to the graphics library outside of the rich text editor tool.

Either way - does this let you actually embed the image into the questions? From the file library demos, it looks like you only get a link. I need to be able to embed the actual image. Does anyone know if this works? What formats are allowed for this?

Hi JeffD,
My answer is probably too late for you, but I'm adding it in case someone else has a similar question. You can include svg files via JavaScript: they have to be on another publicly accessible site, such as in your Dropbox or Github account.
Unfortunately, this doesn't seem to also work for logos (under "Look & Feel"), which can only be added from a Qualtrics library. In my case, this looks very unprofessional because it scales in a terribly pixelated way. Who knows, maybe Qualtrics will allow for svg's at some point.
