I downloaded the Quick start for Travelia. i understand that the temp images or placeholders are just for the quick install. I went to the article that was shown on the landing page and replaced the image with one i uploaded to the a folder i created on the backend under media. It doesn't show on the website even after clearing the cache. It still shows the grey placeholder image.

[Solved] Found my problem, in the article settings under the helix part, it has the grey image, after deleting the regular images showed up. i guess that box overrides the main one.
