[Feature] Thumbnail And Full Size Image Links [Required?] Yes [Notes] 
A thumbnail and full size image link is a technique of having two copies of an image linked together. The first smaller size is shown on the blog post, wrapped in a link that, when clicked, takes the visitor to a larger perspective of the image, usually a higher resolution for viewing of photographic details. A thumbnail image ranges from 3K to 30K depending upon the size, and the full size image could easily be 100K – 300K. If we have one hundred 300K full size photographic images with their accompanying thumbnails, that’s 30 megabytes. So I should probably add another 500 megabytes of file storage to increase photo storage space to 1 gig just to make sure I have plenty of room.
