what is the best free way to resize pictures
There are many variables to your question.
1 - Mac or PC?
2 - Image for upload or existing web link?
3 - Do you need to resize an existing image or are you looking to crop it?
Answers to these will help me give you some ideas.
I would like to know that too, for a existing web link. It makes me feel quite awkward in the chat-rooms at times.
Photoshop allows you do do any manipulation; size, resolution, clipping, etc.
I use irfanview. It's free and easy to use, and very versatile. You can resize, crop, change the resolution, and remove exif data. (Be sure you remove all personal exif data before you post or send any naughty photos!)
