Hello! I've just uploaded a Storyline course into our LMS. During testing, we noticed the course loads slowly in two places, and am unsure why this is happening. Do you have any tips?
Hi Jorgen, thanks for the feedback. I am new to this process, and am not sure what you mean by "if your PNG are more scaled." Can you provide some more info?
I believe Jürgen was referring to scaling down your PNG image files by a factor greater than 90%. If you're planning on scaling them down by more than 90%, his recommendation was to use a third-party image editing tool to resize, and reimport your images back to your project file.
I'm sure Jürgen will chime in if I missed anything!

you have BIG problems with the filesize of your png images
have a look in the folder "mobile" (43.7 MByte png images)
since the storyline version from april 2022 png images are not scales while the publish
you should check all your png in the course, if they are scaled in storyline
scaling 90% is ok, but if your png are more scaled, you should resize the images outside storyline and reimport them

Hello Hajnal,

I don't know your course, but do you really need this picture with 1536 x 2048 Pixel in the course ?
if not, then scale it to the size you need - example to 600x800
result
important: do not crop the transparent unused area - it does not save much and the image must be re-placed in storyline
How to do it:
now you can see how the png is scaled - here 59%
on top you see the size, what you need (here 282x282px)
you can export the image with right click in the timeline > "Show in Media Library..."
you see here the original size - then "Export"
scale the image in an external program, which supports PNG (with alpha channel)
reimport the scaled png (-> "Replace")
then check the image on the slide view - i most cases everything should be ok
UPDATE: if you have the original PNG available, of course you don't have to export it first - you can skip that step
Thank you both for your detailed guidance, Jorgen and Joe!
