I think I have an idea what might be wrong here, the
C:/, it's the way you've written in the '/' after the drive letter. Dokuga won't recognize the address of your Picture folder because directories (also called folders) in Windows and most Operating systems are written with a backslash
\ not a forward-slash one
/.
Example:
For your Pictures folder it should be written like this 'C:\Picture address' and with a backslash and the rest of the folder address after it, and
NOT as
C:/ the forward slash won't be recognized by Dokuga as the location of a folder on your C-drive i.e the site can't find the Pictures folder.
You use the backslash in directory addresses primarily as the C-drive is by default the main root directory in most operating systems, particularly if the PC has only one local hard drive. The default drive address with always start with
C:\ with a backslash \ put in where you had the / forward slash.
You just need to change out that forward-slash '/' for a backslash '\' in the folder address and it should be able to find the picture folder address on your local hard drive so that you can upload stuff.

Long story short just open up your pictures folder on your PC, and then go inside the folder to your picture. Click on your picture, and it's 'location address' should pop-up in the address bar of the Picture folder. Copy and past that address into the browser address box that you use to upload pix to Dokuga, and try to upload again. If that doesn't work it could be another type of error.
P.S: Forward slashes i.e.
/ are only used in URL addresses like this
http://www.dokuga.com/ where as the
\ backslash is used primarily to designate folder addresses on your local hard drive i.e
C:\Folder-Address
