I have an intel iMac running 10.6.7.When I get mail some messages are in small print and also when pictures are sent there is a Question mark where the pictures should be and sometimes there is a message that says "Plugin missing". This has been driving me crazy for a while and I keep asking this question but never get an answer. Hopefully someone will have an answer this time. My Fonts are arial 13 & 14. I have "display remote images in HTML Msgs. I don't know what else to do.
