**The 544 GPT-Image2 cases are catalogued using sequential numeric identifiers (case-1 through case-544) mapped to markdown anchors across two gallery files, with the S44 series specifically indexed in [`docs/gallery-part-2.md`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/docs/gallery-part-2.md) under dedicated subsection headings.**

The freestylefly/awesome-gpt-image-2 repository organizes its comprehensive collection of 544 GPT-Image2 generation cases through a structured markdown-based indexing system. Each case receives a unique numeric identifier that corresponds to specific headings and anchor links within the gallery documentation. This architecture enables direct navigation to individual cases while supporting categorical subgrouping for specialized series like S44.

## The Sequential ID Architecture

Every case in the repository is assigned a **unique numeric identifier** ranging from case-1 to case-544. These IDs serve as the primary catalogue keys throughout the project structure.

The numbering follows a continuous sequence without gaps:

- **Cases 1-165**: Stored in [`docs/gallery-part-1.md`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/docs/gallery-part-1.md)
- **Cases 166-544**: Stored in [`docs/gallery-part-2.md`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/docs/gallery-part-2.md)

Each identifier maps to a markdown anchor in the format `#case-<ID>`, enabling direct linking from external documents or the web interface. For example, case 447 is accessible via the anchor `#case-447`.

## Gallery File Structure

The catalogue is distributed across primary markdown files that serve distinct organizational purposes.

### docs/gallery.md (Central Index)

The [`docs/gallery.md`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/docs/gallery.md) file functions as the **table of contents** for the entire collection. This central index links to every case across both gallery parts, providing the entry point for navigation. According to the repository structure, this file maintains the master reference list that connects users to specific case IDs throughout the documentation.

### docs/gallery-part-1.md (Cases 1-165)

The first gallery partition contains detailed entries for the initial 165 cases. Within this file, each case appears as a markdown heading using the format `## Case <NUMBER>` or via anchor tags `#case-<NUMBER>`. This file handles the earliest entries in the sequential catalogue.

### docs/gallery-part-2.md (Cases 166-544)

The second partition holds cases **166 through 544**, including the complete **S44 series**. This file follows the same heading structure as part 1, utilizing `## Case <NUMBER>` headings and `#case-<NUMBER>` anchors. The S44 subgroup is specifically organized within this file under a dedicated "S44" subsection heading.

## The S44 Series Subgroup

The **S44 series** represents a specialized category within the broader catalogue. These cases are not numbered separately but rather occupy specific slots within the global 1-544 sequence.

The S44 mapping follows this pattern:

- **S44-001** corresponds to `#case-447` in [`gallery-part-2.md`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/gallery-part-2.md)
- **S44-002** corresponds to `#case-448` in [`gallery-part-2.md`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/gallery-part-2.md)
- *(Continuing sequentially through the series)*

All S44 entries are grouped together under the **"S44" subsection** inside the gallery markdown, making it possible to browse the entire series while maintaining their position within the global numeric sequence. The live site at `https://gpt-image2.canghe.ai` mirrors this structure, offering a filter for "S44" that displays the same set of case IDs.

## Accessing Cases Programmatically

You can generate direct links and extract case information using the repository's predictable naming conventions.

To build a direct URL to any case, including S44 entries:

```javascript
// Example: Build a direct URL to an S44 case (case-447)
const caseId = 447;
const url = `https://github.com/freestylefly/awesome-gpt-image-2/blob/main/docs/gallery-part-2.md#case-${caseId}`;
console.log(url);
// → https://github.com/freestylefly/awesome-gpt-image-2/blob/main/docs/gallery-part-2.md#case-447

```

To retrieve markdown headings programmatically:

```python

# Example: Retrieve the markdown heading for an S44 case using a simple regex

import re, pathlib

def get_case_heading(case_id):
    path = pathlib.Path('docs/gallery-part-2.md')
    text = path.read_text(encoding='utf-8')
    match = re.search(rf'^(#+\s+Case\s+{case_id})', text, re.M)
    return match.group(1) if match else None

print(get_case_heading(447))

# → "## Case 447"

```

## Supporting Data Files

The catalogue references structured prompt templates stored in **[`data/style-library.json`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/data/style-library.json)**. This file contains the generation parameters and style definitions that the various cases, including the S44 series, utilize for image creation.

## Summary

- The 544 GPT-Image2 cases use **sequential numeric IDs** (1-544) as their primary catalogue keys.
- Cases are split across **[`docs/gallery-part-1.md`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/docs/gallery-part-1.md)** (1-165) and **[`docs/gallery-part-2.md`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/docs/gallery-part-2.md)** (166-544).
- Each case is accessible via markdown anchors in the format `#case-<ID>`.
- The **S44 series** occupies cases 447+ within [`gallery-part-2.md`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/gallery-part-2.md) and is grouped under a dedicated subsection.
- **[`docs/gallery.md`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/docs/gallery.md)** serves as the central index linking to all 544 cases.
- **[`data/style-library.json`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/data/style-library.json)** stores the prompt templates referenced by the catalogue entries.

## Frequently Asked Questions

### What is the S44 series in the GPT-Image2 gallery?

The S44 series is a specialized subgroup within the 544-case collection that uses the standard numeric identification system. Rather than maintaining a separate numbering scheme, S44 cases occupy specific slots in the global sequence starting at case 447 (S44-001). These entries are organized under a dedicated "S44" subsection in [`docs/gallery-part-2.md`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/docs/gallery-part-2.md) and can be filtered separately on the live web interface at `gpt-image2.canghe.ai`.

### How do I link directly to a specific case number?

Direct linking uses the markdown anchor format `#case-<ID>`. For cases 166-544 (including all S44 entries), construct URLs pointing to [`docs/gallery-part-2.md`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/docs/gallery-part-2.md). For example, case 447 uses the anchor `https://github.com/freestylefly/awesome-gpt-image-2/blob/main/docs/gallery-part-2.md#case-447`. Cases 1-165 use the same anchor format but within [`gallery-part-1.md`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/gallery-part-1.md).

### Where are the prompt templates stored for these cases?

The structured prompt templates and style definitions referenced by the 544 cases are stored in **[`data/style-library.json`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/data/style-library.json)**. This JSON file contains the generation parameters that correspond to the case IDs documented in the gallery markdown files.

### Why are the cases split across two markdown files?

The cases are partitioned into two files based on ID ranges to optimize file size and loading performance. [`docs/gallery-part-1.md`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/docs/gallery-part-1.md) handles cases 1-165, while [`docs/gallery-part-2.md`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/docs/gallery-part-2.md) manages cases 166-544. This division keeps individual file sizes manageable while preserving the sequential numeric catalogue that spans both documents.
