this  is  my  sintaxis:
<img id='ASGROW' src="{!IF(relatedTo.NPS_Brand_Cultivo__c  =='ASGROW',"https://monsanto-lan--qa.cs40.my.salesforce.com/015a0000003SrsD","")}" alt="" height="{!IF(relatedTo.NPS_Brand_Cultivo__c  =='ASGROW',"96","0")}" width="{!IF(relatedTo.NPS_Brand_Cultivo__c  =='ASGROW',"160","0")}" />
  <img id='DekalbImg' src="{!IF(relatedTo.NPS_Brand_Cultivo__c =='DEKALB',"https://monsanto-lan--qa.cs40.my.salesforce.com/015540000004pim","")}" alt="" height="{!IF(relatedTo.NPS_Brand_Cultivo__c  =='DEKALB',"96","0")}" width="{!IF(relatedTo.NPS_Brand_Cultivo__c  =='DEKALB',"145","0")}" />
