[vlmc-devel] [VLMC] #133: Import single images

[Rohit Yadav]

On a quick note, if I remove space from the file and make sure none of the
directories have a space, this image is read correctly and imported to
project, in VLMC.
viz.
media/Nakshatra/Wallpapers/image%20%20vlmc-crashes-with.jpg
to
media/Nakshatra/Wallpapers/image-vlmc-crashes-with.jpg

Best.
