Photos should be made smaller, and optimized in for best SEO.
1. Resize the photos
- I use DCE AutoEnhance 2.1 to reduce the size to less than 150 Kilobytes, 90 Q and 50 Minimun, with a normal size that fits in a box 640 x 640, trying to make a 640 x 480 or 480 x 640 photo.
2. Remove the EXIF data
3. Optimize and validate the HTML
- Use W3C.org to Validate the HTML
