I'm not able to successfully insert images in Zoho Show. When I attempt to insert one, it always appears stretched and way too pixelated. It looks primitive and difficult to read, especially because the images I'm inserting are maths plots. 

I tried resizing the image, but it only makes the pixelisation problem worse. 

Is there a workaround to successfully insert an image in Show? This is a make-break feature for me. So if I can't add images that look at least half-decent, I'll have to resort to OpenOffice or PowerPoint.
