kcm_sddm allows user to choose and set custom background image for login screen. We can select custom background but it is not used by login screen.
As discussed on IRC, the problem here is that custom image has to be readable by all users (as sddm-greater uses sddm user) but by default such images are readable only by current user.
Some suggested workaround might be to move custom backgraound image to some global directory.
Steps to Reproduce:
1. Open System Setting -> Startup & Shutdown -> Login Screen (SDDM)
2. Choose custom background image and apply changes
3. Relogin or reboot
After logout or reboot, default background is still in use.
Custom background image should be used.
Two minor additions:
1. To reproduce, I had to enter my sudo password.
2. On re-boot, not only was the default background still in use, my custom background was removed from the customize theme area.

I can also vouch this happens with the sddm-kcm package for arch linux. ( https://www.archlinux.org/packages/extra/x86_64/sddm-kcm/ )
I can confirm this behavior
Any news on this ?
Seems to be OK (fixed ?) in Kubuntu 15.10.
There's a known issue here.
If you have the image in something any user can read, that works great.
However, if you have your homedir not readable from outside, or an encrypted home directory or remote storage then SDDM fails to load it. We set the setting fine, but that's not always enough.
On different setups we see different things.
I need to look at copying the image into /var somewhere.
I can confirm that this is caused by permissions.
I first had the issue (that was as well present in KDM) and solved it by just moving my custom wallpaperst into /usr/share/wallpaper but basically every location that is readable would do.
I would not copy it somewhere as this opens up cleanup issueas and so on. I'd go for a hint to the user.
On Kubuntu 15.10 with Plasma 5.4 even with a picture in the home folder that's not working now
I can also confirm on Kubuntu 15.10 x64 beta. The locked screen will show the custom background wallpaper just fine, but the login screen (either after logging out or rebooting the PC) will not. Wallpaper is in a dropbox folder within the home directory.
Just a little reminder that need to be fixed. It's still present on Kubuntu 16.04 Daily.
That doesn't work with my tests with an image in /home and in /usr/share/wallpapers/Next/contents/images.
Again a little reminder ;)
Also getting the same problem. 5.5.1 on Arch x64.
I also have this bug on manjaro kde (plasma 5.5.2).
In the past changing image worked (a few months ago) but since some time only default ssdm wallpapers are shown and cannot be changed in settings.
A reminder for this that need to be fixed.
Please don't do "a reminder" emails.
So please fix it ;)

Hello David there is no activity for a month on the link you gave.
Don't forget :D

Why not? I don't have any idea what that "reviewboard" link is, but (a) I don't have an account there and (b) it's not "bugs.kde.org" which I've been using for (OMG!) two decades. If you won't update bugs.kde.org with status, then you're not interacting with the community.
And, fwiw, it's not fixed.

Here's a work around....
Select a theme for sddm (in my case i only have the default "breeze"), hit clear image on the background selection button, then select your desire image afterward.
Bear in mind this will only change sddm background, "K" animation that comes after it and the "lock screen" background need to be change separately.
I'm thinking using KDE again but will this be fixed ?
*** Bug 364329 has been marked as a duplicate of this bug. ***
Awesome ! Thank you David.
I upgraded to 5.8 now. The fix seems to have introduced a little
regression in the settings dialog itself. When I set a background image
it (finally) shows up on the login screen. But when I close and reopen
the settings dialog, the "set background image" button always shows a
default image icon and not the actually selected image.
Besides that, the login screen still shows the default user avatar and
not my actual avatar, but that is probably a different issue.
I can confirm this bug in sddm kcm, Janek.
Here are my bug reports about avatar issue
This broke again after updating from 5.8.5 to 5.9.0
The default blue background is used even if picking an image from a user pictures folder and entering the sudo password.
I can confirm this. I had a wallpaper set before 5.9.0 and now it's gone.
Hah, that's interesting. Loading an image from /usr/share/wallpapers does not work either. Seems to be a different bug, then.

Maybe this: Bug 370521 - [Regresion] SDDM breeze theme unable to change backgound.
