In Visokio Server I updated some images of a iok file (embeded images, like company logos), and I can see them ok. Then I publish the iok and open it on another machine and I still see the old images. I tried to "clear online ressource cache" unsuccessfully.
Go to -> "Settings" > "Images" > "Modify image set..."
Click on "Refresh Embedded Images" (Note that it will remove any embedded images in this image set, causing them to be recreated and re-embedded from the original images when you next save. If the original images are unavailable, your images may be lost forever)
I think the problem is not the published iok because when I open the published file on the server the images are ok. The problem is that when I open the same file on the client machine (using free viewer) I see the old images. Is there a cache to clear in the free viewer?
If those images are embedded into the IOK file the free viewer will open them from the file, so you don't need to clear any cache. Else if you have an IOK file with images located on a remote location, you may need to clear the online resource cache in the free viewer.
