Ability to add automatic images with post titles on them

[Souravgoswami]

Currently an article must have an index image. But we can change the behaviour and we can:

Technical Overview:

• Seed a random number from the article date (even if it is missing)
• Generate a random image index for that article (no matter if the page is refreshed, or all articles are re-generated)
• The random number image will be shown. There will be automatic text as well.
• The post title will be attached to the image.
• Hovering on the image will look like other images, the image with the text will zoom

From User Perspective

If they don't provide the image, it will put a random image there that will not be changed ever, unless the post date is modified, or a new image is added. The image will also have a title on them. They don't have to think about anything, it's all automatic.

Hi @Sergyenko, based on date, we can generate a random unique image for each posts, that will retain forever until the date of the post is added / edited. It works even if the date value is missing.

Here in this image, I have commented out the dates and images of the posts, and it generates and adds random images (from a directory) for them:

So based on that random number, we can insert an image in the post, if the user misses the images. It will append the title to the image as well. What do you think?

I really like the idea, let's make a short demo and see how it's going to fit

Hi, this commit adds the ability to add such random images to the posts. This only works when the preview_image: ... key is missing from the posts.
