Save Image with Metadata v099d

This is the one the pack is named after. Save Image with Metadata v099d is the flagship output node - the older, full-featured sibling of the Simple version - and it's the most powerful image saver you'll find in a custom node, with one very specific personality: it's built for people who hand their ComfyUI output to Adobe software. It saves PNG, JPG, WebP, TIFF, APNG, SVG, and PSD; it writes 16-bit PNGs with ICC color profiles; it can pack your image into a real Photoshop file with named, blended layers; and it can write your metadata everywhere at once - embedded, XMP sidecar, text file, and database.

Start with the essentials: images, filename_prefix (tokens like %date:yyyy-MM-dd%), and file_format with seven choices. Then the file-management group mirrors the Simple node - custom_output_directory/output_path_mode, filename_format, quality_preset, color_profile, rendering_intent, bit_depth (16-bit is PNG-only), alpha_mode/matte_color, APNG fps/loops. The metadata section is the same core: enable_metadata, title/project/description/creator/copyright/keywords, custom_metadata (JSON), auto_extract_generation_params (defaults on - walks your graph for prompts, model, sampler, CFG, seed, LoRAs), include_node_details, and the four write targets (save_embedded, save_workflow_as_json, save_xmp, save_txt, save_db).

Then it diverges with the features Simple doesn't have. PSD layer support: two mask layers (mask_layer_1/mask_layer_2 with names, blend modes, and 0–255 opacity) and two overlay layers (overlay_layer_1/overlay_layer_2, same options), gated by include_mask_layers. Wire a mask or overlay image in, and the PSD you save contains real named layers with blend modes - composable in Photoshop later. A second copy: additional_format saves a web-friendly JPG alongside your master PNG (with additional_format_suffix, quality, and its own color profile). SVG options for the SVG format path: svg_colormode, svg_hierarchical, svg_mode (spline/polygon/none). And enable_runtime_hooks - the pack's most advanced feature: it hooks into node execution to capture what actually ran, which matters in conditional workflows where a static graph scan can't know which branch executed. Auto = read config.json; enabling it the first time may require a ComfyUI restart (or set AAA_METADATA_ENABLE_HOOKS=true).

Outputs are images and filepath - same as Simple, and filepath feeds the pack's Query/Debugger nodes.

Honest guidance: start with the Simple node if you don't need layers. Come here for the specific things only this node does - PSD with real layers, 16-bit PNG, the second-copy feature, and runtime hooks. The trade-offs are real: it's a bigger surface area, some options only apply to certain formats (bit_depth, the SVG trio, APNG settings), and the pack is a one-author effort where docs run ahead of community validation. Set save_txt and XMP off if you don't want three files per image. But for a color-managed, metadata-complete, Adobe-friendly save, there isn't a better node in the ecosystem.

Install the pack and restart:

cd ComfyUI/custom_nodes
git clone https://github.com/EricRollei/AAA_Metadata_System
cd AAA_Metadata_System
pip install -r requirements.txt

Find it under Eric's Nodes → Output, try file_format = psd with one overlay layer wired in, and watch it open in Photoshop with the layer intact. That moment sells the pack.
