Image Size and Pixels I am baffeled - I was reading the Q&A section on Image size and removing the check mark from Resample Image, so I did this the next time I started to size an image, that's when the problem started. When I removed the check mark I could no longer use the pixel dimension box. I can only use the print size box - but when I changed the size of the image to fit the requirement of 750x500 so I can send a photo in to the contest, the resolution goes too high. And if I change the resolution back to the 72 pixil then the size of the photo is way too big to upload - over 5M. I hope some one can help me with this. Thank You.

I've been telling folks NOT to check Resample in situations in which you want the full digital capture the camera can deliver. You want the full image if you'll want to print it, or if you want to archive all the digital information for later. Typically, a digital camera set to its best or near best quality will give you a 72 ppi image, but with impractically large image dimensions, like 14- by 21 inches. If either of the conditions in the first paragraph applies, what you want to do is to scrunch the pixels into a smaller space without throwing any away. You do that by unchecking Resample, checking Contrain Proportions, and set one dimension to the size you would print. Set either the length to, for example 7, or the width to 5. It doesn't matter which one, because the other will be scaled proportionally for you. At this point, save your full image into an archive file of your choice, your hard drive or a CD. Then, check Resample. You are going to be throwing out pixels considered to be non-essential to the structural and color integrity of the image. Does this scare you? Good, it should. No problem if you archived the whole file earlier. In the resolution block, change it to 72, or 75, somewhere close. This reduction is a two step process. You just changed the density of the pixels. Now change the lengh of the image to 750 pixels. The width will fall into place. SAVE AS a JPEG. When the program asks you what compression level, I'd tell it 10. This web site probably compresses them further, but 10 seems to work for me. If you have problems, come back at me. We will get you through this.

Thank You So Much, Doug, I'll try that and let you know how I do.

When I save images for the web, I change the image size and save the new, smaller image to my desktop. Then when I go to close the original (after I'm done saving my web image) it asks if I want to save the changes. I don't, that way I have a true original. If I'm printing it for someone, then I save another larger copy, but don't save the original. That way, if they think it's too light/dark or whatever, I have my original to work from.
