Finish Image Posting Features

[CalderJohnson]

Describe Problem

We have the image gallery set up for adding images associated with events, and we have the image URL feature in highlights allowing a URL to be added for the thumbnail of a post that is in place above the post. We need to merge these features together and apply the functionality in both tabs.

Suggest Solution

In highlights, we need to add a gallery for each post just like in events. We need to have the ability to mark one as thumbnail to appear above a post in the main feed (the place it appears is already implemented). We need clicking the thumbnail to take you to the complete image gallery page associated with that highlight.

In events, we need to add thumbnails above event postings (port the code over from highlights), the gallery is already in place but we need the ability for the one marked as thumbnail to appear above the event posting in the main feed

We also need the view gallery button to not show up if there are no associated images and the viewer does not have permission to upload images.
