WobblePic v1.0.5 is a major milestone — the first 1.x release! This version introduces the Ad-Free License system, a premium directory tree panel, expanded format support, and significant performance improvements under the hood.

New Features

Ad-Free License

WobblePic is and always will be free to use. Starting with v1.0.5, you can optionally purchase an Ad-Free License for a one-time payment of $3 to remove all in-app advertisements and unlock premium features.

  • Payments are processed securely through Lemon Squeezy
  • A license key is delivered immediately via email
  • One key works on up to 3 devices, valid for all future versions
  • License is stored in the Windows registry — survives reinstalls
  • Automatic background re-validation every 7 days (graceful offline handling)

Directory Tree (Premium)

With the Ad-Free License active, the ad banner area transforms into a full directory tree panel:

  • “This PC” root node with all drives listed (volume label + drive letter)
  • Lazy-loaded child nodes with caching — only scans directories when opened
  • Windows system icons for each folder (including special folder icons)
  • Current folder auto-highlighted with ancestor nodes expanded
  • Right-click context menu: Open in Explorer, New Folder, Cut/Copy/Paste, Rename, Delete
  • Splitter between tree and file list for adjustable height
  • Hidden/system/inaccessible folders are automatically filtered

Panel Customization (Premium)

  • Drag to resize — Adjust the panel width by dragging its right edge
  • Ctrl+B — Toggle the panel visibility (hide/show)
  • Panel state saved — Width, tree height, and visibility are remembered in settings.json

New Image Formats

WobblePic now supports additional modern image formats:

  • AVIF — AV1-based image format, excellent compression
  • HEIC / HEIF — Apple’s default photo format
  • JFIF — JPEG File Interchange Format

Full format list: JPG, JFIF, PNG, BMP, GIF, WebP, TIFF, AVIF, HEIC/HEIF

Improvements

SharedMemory IPC

SAM2 encoder output (~16MB of image embeddings) is now transferred between the main process and worker process using SharedMemory instead of multiprocessing.Queue with pickle serialization. This eliminates the serialization overhead entirely — embeddings are written directly to shared memory and read by the other process with zero-copy.

  • 8 fixed SharedMemory slots (16MB each, 128MB total)
  • PID-based naming (wbp_{pid}_{slot}) prevents multi-instance conflicts
  • Windows page-file backed — OS automatically cleans up even on crash

Virtual Index Caching

Both the image pixel cache and SAM2 encoding cache now use virtual index-based slot assignment instead of image_index % 8. This prevents cache slot collisions that could occur when browsing through more than 8 images.

  • Virtual index increments/decrements based on browsing direction
  • Eliminates the edge case where the first and last images in a folder could overwrite each other’s cache slots
  • Applied consistently to both ImageLoader and SegManager caches

Tab Key Behavior

  • I key now toggles the image info overlay (filename, resolution, format, file size)
  • Tab key switches focus between the directory tree and file list
  • Focused panel shows a bright blue selection highlight for clear visual feedback

This PC Drive Navigation

When navigating up from a drive root (e.g., C:\), the file list now shows a “This PC” drive list where you can select any available drive — making it easy to jump between drives without the directory tree.

Bug Fixes

  • Fixed rename failure not showing error details — now displays OS error message in an alert popup
  • Fixed clipboard paste creating duplicate names — auto-numbering applied (e.g., file (2).ext)
  • Fixed context menu appearing on items that shouldn’t have certain options (e.g., no Delete for drives)
  • Improved stability during extended use with large image collections

System Requirements

  • OS: Windows 10 or later (64-bit)
  • GPU: OpenGL 3.3+ (AMD / NVIDIA / Intel with DirectML for SAM2)
  • RAM: 4 GB minimum (8 GB recommended)
  • Disk: ~600 MB (SAM2 model included)

Download
