There is actually quite a bit of work involved with this: If you need to allow your users to upload images from their computer, you will need to get your head around the Paperclip gem [LINK] (or similar). This will store the image on the server. You'll want to determine how big can images be, what to name the images once uploaded and what file formats are permitted to prevent users uploading all sorts of files.

I'm going through a [this video] to install the Paperclip gem on my site. Got to the last step but its returning the following error, not sure where I'm going wrong..

When I'm trying to upload image to database via paperclip, it always ignore the image column. I'm not sure why it doesn't work, I did lots of research about the paperclip, e.g. github [LINK] , [this video] and did exactly the same as those tutorials.
