hot mail, gmail issues


New Email
bought a new computer, windows 7. old system is XP, outlook express mail, and has worked very well for me. no problems at all.
outlook is gone with 7, hotmail is in. Text size is 10 point by default and cannot be changed. To small for me, don't like recommended alternative.
Switched to Gmail which offers limited choice of text/fonts and I'm ok with that.
A recent Google change, prevents pictures in an email from being forwarded. Security reasons. Empty box with red X is all that comes through.
Question. Will I incurr thie same if I switch to Yahoo mail.
Do I take new computer, install XP, if possible, and go on my merry way.
