You understood it correctly. Note that since 5.7 you can use qOverload which makes the code easier to read.

Hi, Do you mean something like the RSS feed ?

The workaround that appends a suffix to the requested image does the trick: image.source = "image://images/myImage?id=" + Math.random() but it's quite dirty. I wonder if there is a more elegant way (i.e. using signals) to keep the image source updated.

@mcosta Thank you it all finally working fine :)
