Created picture keeps spinning

[Jxstitch]

After selecting my picture, it says it is created and may take several minutes.  The "thinking" icon just keeps spinning and I never see the pictures.  I have used my PC and phone and it does the same thing.

This can have several causes:

• Your browser blocks downloads of files
• The internet connection is slow and the download aborts before it is completed
• The pattern is generated at maximum resolution with maximum amount of colors and needs too much time or memory to be generated
