Couple of thoughts here, though they will never get around the limits imposed by ISPs.
You could use Photobucket, which is free. Upload to PB and you have a web based photosite. Second idea, is to get Irfanview, which is also free and is a cracking tool for anyone dealing with Pictures/albums etc. IV will let you resize easily to your hearts content, allowing you to email in confidence.
I do know what you mean. My own camera shaots can be up to six and occasionally seven Mb per pop and very few would get through, were I to try and email them.
