…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.

Take the and put it in the images question load. Then override the
local system user.

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