I was trying to find a simpler way to upload Gifs and not have to go back to the spreadsheet to relink the image via a folder path formula...I figured there was a way to extract the Gif file name and link it directly in the app. So here is my solution.
Tried to reply on another board but wanted to make sure this solution was out there lol
Appsheet is expecting a link to the folder and the file name... something like this:
Foldername/filename.gif
That's why you have to make sure your file name is exact and that there is a backslash after the folder name. Luckily, using a "File" column preserves the original file name for your gif just enough so that you can somewhat easily extract the new file name that appsheet generates when uploading.
