Do you have "paint" on your computer? Some computers come with it or something similar. Click on "start" or programs to see if you have it. Once in paint or a similar freebie program I click on "file", "open" then look for my picture. I click on the picture and it opens in paint. I then click on "resize" and then "pixels". I usually change my pixels to around 1000 or 500. See what your picture pixel is and put in a smaller number.

I don't reduce anything. I upload to Mediafire and they offer three different sizes for viewing. Large is the original size. Small is significantly larger than a thumbnail. Medium is in between (duh!). I have been linking to the medium sized image. I hope it works okay for y'all. My normal monitor is huge but I try to keep my windows down to normal sizes so I don't make mistakes like that. Again, I can't be sure though.

I find Irfanview to be really good for this. The program is free and quite small. If you ever decide to do more with Irfanview you should also download in install the plugins. Open Irfanview, click File click Batch/Conversion rename... and follow along in the new window. You need to do landscapes separate from portraits but I am sure you are aware of that anyway.

I am not a photo aficionado, but I do use Picasa along with Irfanview. In the few issues that I needed help with Picasa I found their Help file user friendly. It is actually on-line with the Toolbar entry only a portal to it. In your case, it took me all of three clicks of the mouse to find the answer to your question. When you have time you may want to visit the site and become familiar with it so it can help you when you need quick answers. DA
