I use this command for locking screen:
i3lock -i /home/freyja/pics/owl.jpg
The screen is locked, but there is no picture (only white background). When called from console the command says:
Could not load image /home/freyja/pics/owl.jpg: out of memory.
What can I do about this? Is memory lacking in whole system (does not seem like it) or just i3-lock has some internal restriction? The picture is big (HD), but the resolution exactly matches my screen, so I wouldn't like to use a smaller one.
