We want to add a file field to a component and upload a file. I'm going to use this Demo component. It got a few Admin Views, we've got the area Look. I got a Site View, Looks and Looking. I'm going to add this field to the Look Admin View. I first need to create the field [00:00:32](https://www.youtube.com/watch?v=o482sK4DxkM&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h00m32s) and we need to look at the steps that will need to implement. Currently JCB doesn't out of the box address this. We might think of doing this maybe in the future but because of some of the security risks, it's best you do this yourself.

So you're uploading a file. The Fieldtypes you want to use already exists. So if you go to Fieldtypes, there is a field called File.

It shows you a whole lot of attributes, their values, some of the descriptions, but also shows you where to get more info on this. It's always good to do that. We are in Form field.

It now has this new 'accept' parameter, which is a nice little extra which wasn't available when I first set it up. If yours doesn't have it, you will see that I [00:02:23](https://www.youtube.com/watch?v=o482sK4DxkM&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h02m23s) have since added it.

I might as well add it now. Under size, let's add that new attributes. So it's 'accept', the value I'm going to leave it to be in 'image' and can be changed. Let's give it some information as regarding description. Copy that and place in here(see video). We got this new attribute set. Those of you running the latest release of JCB, might already have this there. It only gets added if you do a fresh install. It doesn't update the database with these values.
