SP Easy Image Gallery

Hello,
I am working with the Easy Image Gallery. In joomla 3 i could make an album and publish this.
Now i am working in joomla 4 and i can not get the image in the album.
When i upload the line on the screen says 100% but the little circle keeps circling (uploading).
The picture is stored in the albumfolder.
I see all the pictures in the albumfolder so they are on the right place. But the circle keeps circling and is saying "uploadding" when i close with the save button i see no picture.
What is my mistake, what are i doing wrong?
