I purchased an ascended plan, so I can submit better forms. The file submit button in my form is set to image, but it only seems to upload .jpgs. . . Is this correct?
I need my visitors to upload either .jpgs or .gifs (which may be animated).
Thanks.
This is not a code related issue as you can find out all that you need for this through Wix Support and their pages.
To upload other files than image files like jpegs, then you need to change the type of upload in the buttons own settings.

If you use Wix Forms then see here.

You can use the upload button with code as shown here.
