# Legacy Stable Diffusion WebUI — Summer Update ☀️
|
||
|
||
|
||
|
||
A minimalistic, **JavaScript-free** web interface for Stable Diffusion, designed for compatibility with **legacy web browsers** like Internet Explorer 4, Netscape 4.x, and even Classilla on Mac OS 9.
|
||
Built for long-term access to AI image generation using the AUTOMATIC1111 API — from modern GPUs to vintage clients.
|
||
|
||
---
|
||
|
||
## 🆕 Summer 2025 Update Highlights
|
||
|
||
- 🗂 **File structure cleanup** – Generation, prompt saving, and UI now fully separated for better maintainability.
|
||
- ⏳ **True loading screen** – `loading.php` now displays a loading message before generation starts.
|
||
- 💾 **"Save Prompt" moved to result page** – Save your prompt right after generation from `result.php`.
|
||
- 📉 **Improved compression** – Lowered ImageMagick quality to 75 (from 85) for **90–93% file size reduction**.
|
||
- ✅ **Default sampler set to `Euler a`**, which works especially well with **Illustrious XL** (the recommended model).
|
||
- 🧼 Overall code quality and parameter consistency improved.
|
||

|
||
|
||
## 🧪 Installation
|
||
|
||
1. Start AUTOMATIC1111's WebUI with `--api`
|
||
2. Install PHP and ImageMagick on your web server
|
||
3. Place `index.php`, `loading.php`, `generate.php`, and `result.php` in your web directory
|
||
4. Ensure write permissions for:
|
||
- `saved-prompts.json`
|
||
- Your web server's root directory containing the phpsd files, this is where images will be stored
|
||
5. Access `index.php` from a browser and start generating!
|
||
|

|
||
|
||
## 🧭 Usage Guide
|
||
|
||
1. Open `index.php`
|
||
2. Type your prompt and negative prompt (optional)
|
||
3. Adjust generation parameters
|
||
4. Submit ➜ loading screen ➜ image result
|
||
5. Save your favorite prompts directly from `result.php`
|
||

||
## 🧠 LORA Support
|
||
|
||
Use the syntax:
|
||
|
||
```text
|
||
[lora-name:weight]
|
||
````
|
||
|
||
Example:
|
||
|
||
```text
|
||
a high-detail wizard portrait [wizard-style:0.8]
|
||
```
|
||
|
||
Weight values typically range from `0.1` to `1.0`

## 📸 Image Processing Notes
|
||
|
||
* Generated PNGs are automatically converted to optimized JPGs
|
||
* ImageMagick runs with:
|
||
|
||
```
|
||
-quality 75 -strip -interlace Plane -gaussian-blur 0.05 -sampling-factor 4:2:0
|
||
```
|
||
* Resulting file sizes reduced by \~90–93%, ideal for slow connections and legacy hardware

## 🖼️ Legacy Wallpaper Output
|
||
|
||
Don’t just generate — **decorate**.
|
||
|
||
All generated images are:
|
||
