I have inserted an image on the background of my slide masters. When published to HTML, the image doesn't always appear. The first time I published, the background on the 3rd slide didn't appear when played. I republished and now the 3rd slide background appears, but the 8th slide backgroudn now doesn't appear. SO, it is inconsistently not appearing. When I move backward in the presentation and go back to a slide that didn't have the image, it sometimes appears and sometimes continues to be absent.
Can you show some screenshots? Is this a responsive or a non-responsive project? Which master slides did you use? Did you fill the background of the master slide or just put an image on top of the master slide?
I just put an image on top of the master slide. It is a non-responsive project.
Please try to have it as a real background image. See the screenshot which I posted as answer to Rod.
You only use one master slide?
JACKPOT! Thank you. I made it as a real background image using the reference you provided and it worked! I really appreciate everyone's input.
If this image is an SVG, try replacing it with a PNG or JPG.
It is not possible to use a SVG as background in a master slide. Only bitmap images are possible.
Are we sure about that? I have been able to put SVG logos on the Main Master slide and it was visible at runtime. In the end I opted for a PNG version of the same logo because the SVG shows a slight 'glitch' on each slide where it appears as the browser has to render the SVG from the code each time, causing it to be invisible for a split second. But it did work.
Yes, I am very sure. You can use a SVG ON a master slide, but never as background:
I had several SVGs in the Library, no way to select them.
