Google’s Reverse Image Search has an option to search from an image URL, instead of uploading an image.
And images stored in AppSheet can be shared with a public URL–
IF– Secure image access is turned OFF.
SECURITY>OPTIONS
By adding the public image URL to the end of the Google Reverse Image Search URL, a reverse image search can be opened from an action:
"https://www.google.com/searchbyimage?&image_url=" &
ENCODEURL(CONCATENATE(
"https://www.appsheet.com/template/gettablefileurl?appName=",
"YOUR_APP_NAME",
"&tableName=",
"YOUR_TABLE_NAME",
"&fileName="
,[IMAGE_COLUMN_NAME]))
