Hi,

You can form a string within while loop which contains comma seperated HTML tags and then you can check if that string contains img tag as below:

Intranet_News__c obj = [select Story__c from Intranet_News__c where Id = 'a2Nc0000000DL3H'];

string strRichtext = obj.Story__c;
string strTags = '';
while(strRichtext.indexOf('<') > -1 && strRichtext.indexOf('>') > -1)
{
   Integer i =  strRichtext.indexOf('<');
   Integer j = strRichtext.indexOf('>');
  string strtobeReplaced = strRichtext.substring(i, j+1);
 strTags = (strTags == '') ? strtobeReplaced : strTags + ', '+strtobeReplaced;
  strRichtext = strRichtext.replace(strtobeReplaced, '');

}
if(strTags.indexOf('<img>') > -1)
//This means the Rich text field contains image.

Thanks
