• Card border may be highlighted in red

Common Failure Reasons:

2. Read the specific error reason
3. Determine if the issue can be resolved

Error Messages Examples:

• "No text detected" → Image may not contain readable text
• "File upload failed" → Network issue, try removing and re-uploading
• "Insufficient credits" → Purchase more credits to continue
• "Processing timeout" → Image too complex, try simplifying or splitting

8.3 Retry Failed Images

Tips for Best Results

4. File Naming: Use clear, sequential filenames (e.g., page-01.jpg, page-02.jpg) for better organization

Upload Strategy

1. Start Small: Test with 2-3 images first to verify settings
2. Check Results: Review initial translations before uploading a full batch
3. Gradual Addition: Upload images in groups rather than all at once
4. Monitor Limits: Keep track of the 1000-image maximum

Translation Settings

1. Choose Appropriate Type: Match translation type to your content for best results
2. Manga Mode for Comics: Always use "Manga Translation" for comics and graphic novels
3. Verify Languages: Double-check source and target languages before starting
4. Auto-Detect for Mixed: Use Auto-Detect when unsure about source language

Download Management

1. Review Before Download: Check all images in lightbox before bulk downloading
2. Download Both Versions: Use "Download All (ZIP)" when archiving projects
3. Organized Storage: Maintain separate folders for different batch projects
4. Backup Originals: Keep original images in a safe location

Troubleshooting

Common Issues and Solutions

Issue: "Maximum 1000 files limit reached"

Solution:

• Remove some images from the current batch
• Process current batch first, then upload more
• For larger projects, use multiple batches

Issue: "Some images failed to upload"

Possible Causes:

• File format not supported → Use JPG, PNG, WebP, or GIF
• File size too large → Compress images to under 10MB
• Network interruption → Check internet connection and retry

Solution:

1. Note which files failed (check error messages)
2. Verify file formats and sizes
3. Remove failed files and re-upload

Issue: "Translation is very slow"

Possible Causes:

• Large batch size (close to 1000 images)
• High server load
• Complex images with lots of text
• Network speed

Solution:

• Use smaller batches (10-15 images)
• Process during off-peak hours
• Use "Pause" and "Resume" to manage system resources
• Check your internet connection speed

Issue: "Translated text looks wrong or garbled"

Possible Causes:

• Incorrect source language selected
• Low image quality
• Complex fonts or handwriting
• OCR misreading characters

Solution:

1. Verify source language is correct (try Auto Detect)
2. Use higher quality images
3. Try different translation type
4. For handwritten text, expect lower accuracy

Issue: "Download ZIP file is empty or corrupted"

Possible Causes:

• Browser download interrupted
• Ad blocker interfering
• Insufficient disk space

Solution:

1. Disable ad blockers temporarily
2. Try downloading again
3. Check available disk space
4. Try a different browser
5. Download individual images instead

Issue: "Lightbox view mode buttons not working"

Solution:

• Ensure JavaScript is enabled
• Try refreshing the page
• Close and reopen lightbox
• Clear browser cache

Credit System for Batch Translation

How Credits Work

• Cost per Image: 1 credit per image
• Batch Cost: Total images × 1 credit
• Example: 15 images = 15 credits

Credit Display

Before starting translation:

• Clear indication of total credits needed
• Warning if insufficient credits
• Current credit balance shown

What Happens with Insufficient Credits

1. Mid-Batch Depletion:

   • Translation pauses automatically
   • Completed images are saved
   • Remaining images stay in "Pending"
   • Can resume after purchasing credits

2. Preventing Issues:

   • Check credit balance before large batches
   • Purchase extra credits for projects
   • Use smaller test batches first

Comparison: Batch vs Single Image Translator

When to Use Batch Translator

• Managing a project with multiple related images

When to Use Single Image Translator

• Translating just one image
• Experimenting with different translation types
• Mixed content types requiring different settings
