Re: image override*

> ...the image will override the some user...
Maybe its just me but I have a problem understanding what you mean with
that sentence. If you can''t describe your problem clearly I doubt
you''ll
get an answer.

I have some apps where I take care of uploads myself but why aren''t you
using some of the upload gems available? Like paperclip or carrierwave
for example? They do save work.

Cheers.

Using session folder, the local system multiple idea override.  Then 
system the local folder in the session upload.
