What you could do is make use of the Multiple Images column to upload all of your images in one shot, and then use a Single Value column to extract one for each day of the year.
Do it like this:
- Start by adding a column to number all the rows in your table from 0-365 (see here for an easy way to do that).
- Add a Multiple Images column and upload all of your images into that column using an Image Picker
- Add a Single Value column that applies the Multiple Images column to all rows in your table.
- Add a second Single Value column, and configure it to take “From Start → Row Number” from the first Single Value column
- Each of the rows in your table should now contain a separate image
The only gotcha with the above is that if you have specific images for each day, then you would need to take care to add them in the correct order.
