In my blog DevPack, I am using substitution codes that can be inserted into Text or Typography components and the Devpack will substitute those codes with the metadata values from a displayed post.
The codes (at the moment; there will be more) are:
- **{DATETIME}**
- **{CATEGORY}**
- **{TITLE}**
- **{SUMMARY}**
The problem comes with an image as there is now way to specify **{IMAGE}** in an Image component and override it with the image from the metadata.
So I am searching for **files/image-square.png** and replacing that with the image link from the metadata. Whilst this works well, it is obviously risky going forward if that default filename was to change?
I was wondering whether there was a way to manually input the the image link into the Image component to avoid this, so that **{IMAGE}** could be used?
Conversely, do I need to be worried by this?

Just an update on this, I did caught out! If you have a different web page at the root level, the default image files are name with the filename added to the front. So if you have a webpage called **blogging.php** , the associated default image file is named **blogging\_files/image-square.png**.
Anyway, with the assistance of ChatGPT, I now just check for **image-square.png** with any parent folder and that handles both cases. 🙂
