For the feedback section it is better to add the EXIF data separately because for some people it does not show up automatically. Also limit your photos to 1 per post and 1 post a day. This will give you a better chance of people telling you what they think of your photo.
How to add a photo to a post.
Guidelines to adding a photo to your post.
1. Resize photo to 1000px on the long side.
2. Resolution set to 72ppi (Pixels Per Inch)
These guidelines will be good for viewing on a computer but will not be good for printing. This will help safeguard your copyright.
