> there is a bug with standard coverurl setting, if discogs release has multiple covers it adds ALL urls into coverurl.. (e.g. in coverurl you'll get: [http://api-img.discogs.com/....http://api-....discogs.com/](http://api-img.discogs.com/....http://api-img.discogs.com/....http://api-img.discogs.com/)... instead of just 1 URL)

hm, I don't think this is a bug even I am a lot in favor of it. Bug is considered smth delivered not working as described. This is a missing functionality, yes.  
There are a couple of solutions Florian could apply unless he finds smth better.

1. New command **readoutputto ""** It would bring the value of tag already filled before (after **outputto ""** ) to the working area. I have requested several times this feature (which I think will increase the power of WS) but I have not seen any reaction yet. Last time requested in this post [[WS] HELP !!!](https://community.mp3tag.de/t/16672/6).

```
# Coverurl
outputto "coverurl"
json_foreach "images"
    json_select "type"
    if "secondary"
        readoutputto "coverurl" # <<<<<<<<< new code
        if "" # <<<<<<<<< new code
            json_select "uri"
            sayrest
        endif # <<<<<<<<< new code
    endif
json_foreach_end

```

2. New command **json\_foreach\_exit** (as you mentioned) It fits your example but could be insufficient for other cases. E.g. fill the tag only the first time but do not leave the loop.

```
# Coverurl
outputto "coverurl"
json_foreach "images"
    json_select "type"
    if "secondary"
        json_select "uri"
        sayrest
        json_forech_exit # <<<<<<<<< new code
    endif
json_foreach_end</li></ol>

```
