List of Reasons for Inability to Upload Images

If you are trying to upload an image to nbbs (bulletin board script operated under the 'nbbs.biz' domain) and it doesn't work:

• Supported file extensions: jpg/png/gif
• File size: The allowed maximum varies based on bulletin board settings, so check the details on the posting page for capacity.
• The image upload feature may not be enabled by the bulletin board management.
• A bulletin board that has not been used for a long time may restrict postings to text only.
• On a heavily used bulletin board, you might reach 80% of the maximum capacity, which restricts postings to text only.

Deep Dive by Cause: Typical Patterns of Image Upload Failure

1. Unsupported File Extension/Format

Some bulletin boards may restrict the image formats that can be uploaded. For example, it is common for only 'jpg/jpeg', 'png', and 'gif' to be allowed, while formats such as WebP or HEIC may be rejected. If the format is unsupported, symptoms such as "cannot select" or "not reflected after upload" may occur.

2. Exceeding Maximum File Size or Dimensions

There may be settings on the administrator side defining 'maximum file size', 'maximum resolution (height x width)', and 'number of uploads/files'. Exceeding these limits will result in an error. This is particularly common when trying to upload high-resolution images taken with smartphones.

3. Image Posting Disabled in Bulletin Board Settings

The bulletin board administrator may have set a 'no image posting' or 'image posting not allowed without payment/request'. Even if there is a selection box displayed on the posting screen, it may not actually function. Confirmation with the management team is necessary.

4. Issues with Browser, Device, or Connection

JavaScript errors, cookie or local storage restrictions, smartphone browser compatibility, restrictions in the file selection dialog, or temporary instability in the communication environment can cause the upload process to stop mid-way or become unresponsive. Trying a different browser or PC may resolve the issue.

5. Need to Consider Alternative Upload Methods

If the specifications or restrictions of the bulletin board are too strict, and you simply cannot upload, using an alternative method to upload the image and then pasting it into the bulletin board can be effective.

Recommended Alternative: Free Uploader UploadF

If you absolutely cannot upload images on the 'nbbs.biz' bulletin board, one alternative is to use 'UploadF (uploadf.com)'.

Features of UploadF:

• Accessible on both PC and smartphone
• Allows for drag-and-drop uploads
• Free to use, with simultaneous uploads of multiple files allowed
• Extended storage period options, and files can be deleted individually
• Supports many file extensions with high reliability

Specifically, upload the image to UploadF → paste the obtained 'shareable URL' into the bulletin board post to indirectly display the image on the bulletin board. This is a practical method to avoid the frustration of not being able to upload directly to the bulletin board.

Points for Bulletin Board Administrators and Posting Users

When unable to post images to the bulletin board, there are points each party should keep in mind.

Checklist for Administrators

• Image upload settings: Are the allowed formats, maximum sizes, and limitations clearly stated?
• Is the 'image selection area' functioning properly in the posting form (including on smartphones)?
• Is there enough storage capacity on the server side or free space in the upload folder?
• Are clear messages provided in case of upload errors?
• Are alternative methods (e.g., guidance to external uploaders) communicated?

Checklist for Users

• Before posting, is the image within the specified format and size?
• If using smartphone images, should they be 'reduced/converted' as necessary?
• Try a different browser or clear the cache if issues persist.
• If you absolutely cannot post, use external uploaders like UploadF and paste the link.
• Review the bulletin board rules (prohibited extensions/size limits/file counts) in advance.

Conclusion: Address Inability to Upload Images with “Cause Analysis + Alternative Methods”

When images cannot be uploaded to the 'nbbs.biz' bulletin board, first check the four basic points: 'file extension, size, feature activation, and browser environment'. If it still cannot be posted, using the introduced free uploader 'UploadF' is a wise approach to display images on the bulletin board through other means.

In older bulletin boards that have been around for some time, technical specifications and restrictions may not have been updated, so it is also important to maintain a proactive stance such as 'contacting the management' or 'reviewing posting rules'. Enjoy using the bulletin board comfortably.
