>Subject: [PATCH] Bug 26692: Add barcode image generator service for OPAC
>
>Some libraries would like to add a scannable barcode to the patron self
>service area of the opac for patrons who do not have their library cards
>with them. The existing svc/barcode on the staff side should work fine,
>but requires a staff login. It makes sense to duplicate this script
>but only require a valid patron login to use it.
>
>Test Plan:
>1) Apply this patch
>2) Browse to /cgi-bin/koha/svc/barcode?barcode=123456789 from your OPAC address
>3) Note the barcode image
