Storyline course loading slowly in LMS

Hello Hajnal,

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!

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

• before: 4.605 KB (1536x2048)
• after: 780 KB (600x800)

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:

• first make a backup of your .story file !!!!
• now search your biggest problem images - I would search first for all pngs bigger than 2.000 KB
• double click the images in the folder "mobile", now search the image on the slides
• mark the image, click "Format", then "Size and Position"

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
