[Pharo-users] is there a better way

[Roelof Wobben via Pharo-users]

Hello,

I have now this code : https://github.com/RoelofWobben/Rijksmuseam
but it seems to be slow.

Can anyone help me with a way I can use a sort of cache so the page 
looks first at the cache if a image is there .
If so, take the image from there , if not , ask the api for the url of 
the image.
