I have found that my own cell phone provides good images for a website. It is only a 4 megapixel camera and I can email it to myself. Yes, ya still have to crop or set up a lighting area for your pic...but the resizing is easy and converts easily to thumbnails. Digital cameras are HIGH RESOLUTION which is not good for web pages and add excessive weight (kbs and mbs).
We have the technology at our fingertips...so why not put it to good use?
