Image size in Storyline 360
Generally I used the course resolution as a guide. For example, no need to insert a 6000x5000 image into a course that's 720x540. The image is going to scale down to fit the dimensions of the course. Everything gets optimized for web delivery when you publish.
A bigger concern is probably using media that's so large it eats up your memory while in production mode. For the most part that's not an issue with images, but can be with video.
- DPI doesn't matter.
- Image tuner is great for scaling images down in size if you don't have anything else
I find that dpi does matter when inserting images in to Storyline.
Images at 72ppi don't give me the quality I need. Instead I create my images at the actual size I need (Illustrator or Photoshop) with a resolution of 96ppi and scale them down to 75% when I insert them in to Storyline. High quality every time.
This screen grab shows a quick comparison. The difference is subtle but noticible.
I believe that when Storyline publishes a course all images are output at a resolution of 96ppi. If you use images that are 72ppi then those images will be upsampled to 96ppi resulting in a degredation in quality.
There's a difference between DPI and PPI. And that's about as far as I'll take the wonky PI conversation. :)
Oh, I think you find the solution at my problems David (and Tom):
In Photoshop, my images are perfect, but in they are always a little blurred in SL, even while keeping their zoom at 100% (and the Image quality at 100% in Publish Quality Settings). This causes me a lot of difficulty when I need to insert accurate scientific tables, charts and pictures in my slides.
I never thought to put 'em at 96ppi; which I’m going to test right now!
Thanks!

96ppi at 75% has solved the issue for me! Still looks a little soft in preview, but published looks great. Thank you!!!
