In the select query the element should be in the xs:base64 type. Please refer this doc. Here is a sample dataservices configuration for select query.

    <query id="select_testing_query" useConfig="default">
      <sql>SELECT username,password,remoteaddress,result,img FROM public.testing</sql>
      <result element="SAMPLECollection" rowName="SAMPLE">
         <element column="username" name="username" xsdType="xs:string"/>
         <element column="password" name="password" xsdType="xs:string"/>
         <element column="remoteaddress" name="remoteaddress" xsdType="xs:string"/>
         <element column="result" name="result" xsdType="xs:string"/>
         <element column="img" name="img" xsdType="xs:base64"/>
      </result>
  </query>
   <operation name="select_testing_operation">
      <call-query href="select_testing_query"/>
   </operation>
