Posting on Instagram Problem


New Member
For some reason I can no longer post images to my Instagram Account.

I purchased the Engaging Social Media Posts; that consists of 30 .png images.
They are in Google folder.

After 2 successful posts to Instagram I can no longer post these photos.
Some setting must have been inadvertently made - I did make 2 successful post before this happened.
Now I get en error from Instragram when I select an image. I click the + sign on Instagram and click on Browse button.
I select and image, then I get the following error: " Upload failed. Only images can be posted."

I am sure it is something simple to regain access to these images again. I just can't figure out how.
Anyone know how I can fix this?
