Hey everyone. I am not sure how many computer savvy people are on the site, but there is a really good
FREE add on for Windows XP available from Microsoft that lets you resize your pics quite easily right in window explorer by right clicking on them. No need to even open another program. I use it quite a bit when I post here and I do not need to edit in Photoshop or GIMP. (I usually resize to 1024 x 768 for posting here so it fits in most browsers..)
Anywho.. hope this is helpful for someone. Here is a link to the power toys homepage... look for the "image resizer" a little ways down. There are also a few other great add ons there too.
