The old node will still work if its in the workflow but it's marked as deprecated and it may be removed in the future.
The Get Booru Post (Any) Adv. currently should work the exact same way besides 1-2 obvious changes.

Gets the image, tags and original + scaled image dimensions from a given danbooru or e621 post url. Main fetch node showcase url: insert any post url from e621 or danbooru (see Supported sites at the bottom) scale_target_avg: determines what average to scale the image dimensions to. SCALED_WIDTH and SCALED_HEIGHT will then output diffusion-compatible values by keeping the numbers multiples of 64. (e.g.: Use ~1024 for SDXL) img_size: set the size variant of the output image (sizes are in danbooru format, if you select a size unsupported by e621 it will use preview as fallback) format_tags: if set to true the output will format the tags to remove any underscores and adds backslashes infront of parenthesis exclude_tags: excludes tags based on bottom textbox

Tag Wiki Lookup node

Gets the wiki description of a given tag. Output is pretty barebones but it's probably enough for most people. Can be used standalone through the Fetch Wiki button (I wanted to make the output show as markdown like the Markdown Note node but me JS skills are like none) Tag Wiki Lookup node showcase tags: input any tag you want to get the wiki description of booru: select what image board site you want to get the info from extended_info: more of an experimental setting but for danbooru at least it gets rid of related tags and such that is below that Fetch Wiki Button: You don't have to queue to get the wiki description. Since nothing is queued, it will only show the text in a read-only textbox in the node

Danbooru
e621 / e926 / e6ai

You can find a few example workflows in the example_workflows folder. Simply dragging the images into ComfyUI should work.

Useful nodes

Good string join/concatenate node and a bunch of other stuff from KJNodes (required by simple_t2i example workflow) Show Text node and tag autocomplete as well as other possibly useful stuff from ComfyUI-Custom-Scripts Show Any node from ComfyUI-Easy-Use (required by just_the_nodes example workflow)
