Not able to download Image Urls from SDMLS

edit

I am trying to download Image Urls from SDMLS. MLS say i have access for Media Resource.

UserName - 500183 LOGIN Url - http://spn-rets.paragonrels.com/rets/...

When i try to download Image URLS, it says no record found.

Query i am using is below -

http://spn-rets.paragonrels.com/rets/fnisrets.aspx/SPN/search?SearchType=Media&Class=RE_1&Count=1&GroupBy=L_ListingID&Query=(L_ListingID=190013289)&QueryType=DMQL2&Select=MED_sequence,MED_media_url&Limit=100&Offset=0&Format=COMPACT

What is wrong in query ?

Any help would be highly appreciated. :)
