Liz,
I will check out and verify some of my resources and get back to you on tutorials and free-ware.
As to Doug's Tiny URLs, if you look closely, the 1st and 3rd have an added space in them.
Remove the extra space and you should get connected to the site.
Since the site upgrade last year, TR has been adding random spaces to the forum postings.
I'm pretty sure that Paint Shop Pro from JASC will do all that you need.
I use 3 different imaging suites:
Adobe Photoshop Elements
U-Lead Photo Impact
Arcsoft Image Suite.
All of them allow you to resize and convert images to different formats.
I recommend that you only use JPEGs once you are finished with all editing.
Each time you save an edited image as a JPEG, you loose some image data.
Once you have the image cropped and edited as you desire, you can then resize it for both physical size and pixel count (dots per inch).
When you save "as" a JPEG with most software packages, you have the option to choose the compression factor.
For web posting, go ahead and compress the image as far as the software allows.
For your archive, use the least amount of compression. Or, save the image as a TIFF.
