Adding picture to a list using a button rather than having to specify hyperlink

Dear All,

I'm building an auction site where users can add a items. This is done using a custom list containing columns list description, bid$, last bid, and a picture (obviously for the item being auctioned). THis i done using a hyperlink column (I've activated the option to show picture rather than hyperlink).

Is there a way for users adding list items to upload or select a picture (e.g. via a button) rather than having to first add to a picture library and then specify the hyperlink in the list column?

Seems a bit back to front?

Thanks,

MDB
