Image upload failed- file not writable Trying to upload images and get the following error

Upload failed for "filename". The error message was "Error uploading the file: The folder "/var/www/html/imgs/logos/" is not writable"
On the server, check:


if the folder exists? 
Check the folder permissions are set to 777 (could probably reduce to 755)


Within Craft:

In: Settings > Assets > Asset Sources - make sure File System Path and URL fields, have no leading forward slashes e.g.

imgs/logos/
