What?
This is an article to document how I downloaded an image held in a Zoho Creator form, and sent it to an API wanting the publicly accessible link or URL of the image.
Why?
I've got some other articles on handling images in Zoho Creator (see "Sources" below), the most relevant one being my article
Zoho Deluge: Get Image Uploaded in Creator Form which has one method of getting a public link.
My use-case scenario here is that while I could upload the link from Creator to eBay's Picture Services successfully, Shopify would not accept any links I gave it. Why not use the links that eBay returns? Well eBay returns URLs to images that have been resized to 400x400 (even with tweak to return 800x800). I wanted a way to upload my image directly to Shopify in 3024x3024 resolution (or the size that the client wants: iPhone res). I then found that Shopify does accept a Base64Encoded version of the image and the below is how I achieved this.
How?
First-off, let me list the various formats that Zoho Creator says that public link exists.
