Hello, It looks like you upload the same images (max resolution, without optimization) three times and reached the limit.
The best way to use your pictures multiple times is the next:
1) Create an album in our Gallery.
2) Optimize and crop your photos before uploading.
- Try uploading the photos at a maximum size of 1000x1000 pixels and resolution 72 dpi if possible.
- Use "Save as for Web" option in the graphic software you use or
- Use intuitive online service webresizer
3) Upload your photos in your gallery and reuse them in your posts:
- Right-click on your photo in the Gallery and choose "Copy image URL"
- Click on the image icon in the forum thread and paste the URL in the field.
To delete your duplicated content use navigation in your profile.
