Hey there Sitejet with Plesk users,
We recently got a few reports of images not being properly exported from our servers to yours upon publishing. This caused the published website to have missing images.
The re-publishing did not really fix this issue for most users.
After investigating the issue we just deployed a hotfix on the 23rd of October with the Extension-Version 1.3.4 that should prevent this issue to happen again.
If you still have this issue, please first check for updates of your Sitejet Version and Plesk. If you are reporting this is still happening for you, please always provide the Website ID, URL as well as the panel.logs.
Thanks!
