Before You Start

Before creating your Image Gallery QR code, make sure:

  • Your images are final
  • Images are high quality but not too large in file size
  • Images look good on a mobile screen

Very large image files may load slowly for users, especially on mobile networks. Compress images before uploading to keep the gallery snappy.

Common Problems at This Step

❌ "Images are not uploading"

  • File size is too large
  • Slow or unstable internet connection
  • Unsupported file format

Fix: Compress the images, check your connection, and confirm you are using JPG or PNG format.

❌ "Gallery opens slowly"

  • Images are high-resolution and have large file sizes

Fix: Resize or compress images before uploading to reduce load time.

❌ "Images look blurry"

  • Low-quality or heavily compressed images were uploaded

Fix: Use clear, original-resolution images for the best visual result.

Step 4: Add Gallery Details

After uploading images, you can:

  • Add a Gallery Title
  • Add a Description
  • Upload a Thumbnail (optional cover image)

This helps users understand what the gallery is about before they start browsing.

Frequently Asked Questions

Can I add or remove images later?

Yes. Because this is a Dynamic QR Code, you can log in to your QRTRAC dashboard and add, remove, or reorder images at any time. Your printed QR code keeps working without any changes.

What file formats are supported?

QRTRAC supports JPG and PNG image formats. For best results, use high-quality originals and compress them to keep file sizes reasonable before uploading.

Can I track how many people viewed my gallery?

Yes. The analytics dashboard shows real-time scan counts, unique visitors, device types, and geographic locations so you can measure engagement.

Does the gallery work without internet?

No. The scanner needs an active internet connection to load the gallery page. This applies to all dynamic QR codes.

Common Mistakes

  • ❌ Uploading uncompressed, oversized images that slow load time
  • ❌ Using low-quality or blurry images that look bad on mobile
