Improved Post Features

I have 2 categories for this. During post and after posting. During Post Features: The first feature would be the ability to have a text + image post. It is kinda annoying that I have to put all of the text I want in the title when posting with an image. The second feature is image captions. This would just be a simple caption below an image that you can add to give the image more detail. That goes into the third feature, which would be the ability to post multiple images in a single post. I would see it best with having a slideshow type system, with the user clicking arrowing one the left or right side of the posts images to switch between them. That would also be a reason why captions would be important. Now for the after post features. These would be pretty simple, and would include post deletion and post editing. Post deletion is very simple. It would just be the ability to delete a post after it has been posted. The post editing is also a very simple feature. That would just be the ability to edit a post after it is posted, incase if you made a mistake.
