I am new to NPN and have never had any training in photoshop cs5. I would like to know how to resize jepg images to post on web and here on NPN ? I am using a Canon 5d which produces large files if it matters, I did read how to do it in elements but its not the same and im not sure of the process.
I have CS5 and it seems that every task involves too many steps , seems to take the fun out of photography but i do see the benifits I just cant find anyone to help me figure it out around where I live.
Jack, I used to feel that way but have since learned to really enjoy the process. If you think in terms of an entire end to end, image-creating process, Photoshop or post processing is merely the final stage in developing your image. Nothing replaces the experience of actually being in the field and capturing the image, but working the image then becomes a creative and enjoyable part of the process. I enjoy this part of the process because it allows me to relive the experience as I work the image. Just some food for thought.
Photoshop is big and complex, but photographers use only a subset of its features. Sandy's suggestion is an excellent resource; I use it myself. Dave Bostedo has pointed you to a nice article here at NPN.
As for it taking the fun out of of photography, PS's the digital equivalent of darkroom work. Without the smelly chemicals. And it's a lot less complex and not sensitive to temperature.
Here is my steps, seems like alot but simple. Once you are done editing your image in CS5 go to;
File
Save for web and devices
Next window top right set to Jpeg
Set Maxium
Set quality 100% ( may have to reduce depending on where you are posting the image)
Optimized
Check convert to srgb
I use monitor color, my monitor is calibrated.
I use bicubic smoother
Percent I set 100%
Type in your H&W px for image size
then click in the top right 100% box
You will see your new size on the bottom left
Then Save to folder of your choice.
Thats it, once you see and this is it is simple and quick!
Do you have to set the DPI (say 72) also how do you know how big to set height and width are there round about figures for this for landscape style shots ? And why did my photo which was very sharp lose so much sharpness ?

Do you have to set the DPI (say 72)
You can if you want to. The DPI (really PPI, pixels per inch) doesn't change the size on screen (in a web browser) or the file size. It changes the document size which is the printed size.
how do you know how big to set height and width are there round about figures for this for landscape style shots ?
For posting on NPN, set the longest side to 720 pixels (1200 pixels for optional larger file) and let the short side fall where it may. Make sure the file size is under 300KB (500KB for optional larger file).
Jack - Also check my comment on your posted image about DPI.
As far as the sharpness goes, when you shrink an image, you are going from a lot of pixels to a smaller amount. So to determine each final pixel, the software takes a look at all the pixels in the surrounding area and uses an algorithm to make a guess at what the final image pixel should look like in the smaller image. There are different algorithms that can be used, but because there's always some amount of averaging going on, the image almost always gets softer.
There are tons of ways to deal with this in PS... but that may be a topic for you to look up in the future.

How To Prepare Your Images...
It should be very close to what you need to do in CS5. If you still have any questions at all, please feel free to ask!
I'd also urge you to get one of the good CS5 tutorial books. CS5 is full of magic
I'd recommend CS5 for Nature Photographers:

Another link is checking the articles and posts already written here. There was a post written pointing to some helpful and relevant topics here on NPN. Additionally, you can do a search for "sizing" or "resizing" in the Digital or select "All Topics" discussion forums.
