I took some pictures with my digital camera which I plan on posting on my website. Upon viewing them on my computer, I realized the resolutions weren't as good as I wanted. There are some background items that don't show up. I've tried opening Photoshop 7 and using the Zoom tool, but it doesn't realy help. Is there any way for me to sharpen the resolution or is there nothing I can do about it once I've taken the picture?
