I don't know if this is related to the lockdowns that were imposed when the wiki spam came along.

I have a page with two images, Ethernets.svg and L2TPv3.svg, that are supposed to be displayed on https://wiki.ubuntu.com/JonathanFerguson/EthernetInterconnections that were visible prior to the wiki spam events.

When I go to the 'Get Info' link and then click on 'view' for the most recent revion, the images display correctly:  https://wiki.ubuntu.com/JonathanFerguson/EthernetInterconnections?action=recall&rev=29

The images are listed and can be viewed: https://wiki.ubuntu.com/JonathanFerguson/EthernetInterconnections?action=AttachFile

The weird thing is that the raw text for the current page and for revision 29 are identical:
https://wiki.ubuntu.com/JonathanFerguson/EthernetInterconnections?action=raw
https://wiki.ubuntu.com/JonathanFerguson/EthernetInterconnections?action=raw&rev=29

This is the only page that I have edited that has an image attached, so I don't know if this just affects myself.

I guess that a fix could be that I select 'Copy Page' from the 'More Actions:' dropdown menu, to create a backup.  Then I could revert to revision 29.

Before I attempt a fix, I would like to know if this situation needs to be investigated.

By my own investigations looking at the source of the pages using Firefox, the following strings can be entered into the address bar:
view-source:https://wiki.ubuntu.com/JonathanFerguson/EthernetInterconnections
view-source:https://wiki.ubuntu.com/JonathanFerguson/EthernetInterconnections?action=recall&rev=29
Compare present version line 162 with revision 29's line 165
Compare present version line 263 with revision 29's line 266
The file path for the `data` specifier is bogus for the present version page.
