Love the pics --I did the same dont know how to post pics here

There is a tutorial here:

It is not difficult once you get the knack...
Keeping your photos within the size range is the biggest issue.
But that tutorial covers most of the problems.

You can change pixel sizes of photos on your computer.
In Accessories in microsoft windows, there is Paint...which will do that for you. Avatars 85pixel limit, siggie has a limit which shows when you do it, and also the "manage attachments" shows you file size limits. Our software will reduce some to the proper size, but really big things need to be reduced at your end.
