Every p:pic and every p:graphicFrame on a slide now becomes an Artstr image layer pointing at the shared placeholder URL (https://i.postimg.cc/9fY3n60q/example-image-replace-me.png). No binary media is ever decoded from the .pptx package — the user replaces each placeholder with their own URL after import, which keeps imported decks Nostr-publishable out of the box and honours Artstr's "remote URLs only" image model. Pictures (p:pic): - convertPicture reads spPr/xfrm for geometry, resolves the a:blip@r:embed relationship through the slide's _rels file, and uses the original media filename (basename of the relationship Target, URL-decoded) in the layer name: "Image: image3.png". - Missing embed relationship → MISSING_IMAGE_RELATIONSHIP warning; the placeholder still lands. GraphicFrames (p:graphicFrame): - convertGraphicFrame reads xfrm directly off graphicFrame (not spPr — that's a graphicFrame quirk), then dispatches on a:graphic/a:graphicData@uri: • chart → "Chart placeholder: <name>" + UNSUPPORTED_CHART_PLACEHOLDER + placeholders.charts++ • table → "Table placeholder: <name>" + UNSUPPORTED_TABLE_PLACEHOLDER + placeholders.tables++ • diagram → "SmartArt placeholder: <name>" + UNSUPPORTED_SMART_ART_PLACEHOLDER + placeholders.smartArt++ • else → "Unknown object placeholder" + UNSUPPORTED_UNKNOWN_PLACEHOLDER + placeholders.unknown++ walkSpTree now dispatches sp / pic / graphicFrame. readSlideRels loads the per-slide _rels file into a Map<rId, {target,type}> once per slide and passes it through ctx.slideRels. Smoke-tested: - gallery_template_layout_set.pptx: slide 10's chart now appears as 'Chart placeholder: Chart 0' (image layer, postimg URL, 9.3 x 5.85 inches at 1.2, 3.08) with an UNSUPPORTED_CHART_PLACEHOLDER warning in the report. - Synthetic multi-placeholder deck (1 picture + chart + table + SmartArt) exercises every branch: Image: image1.png from rels basename; chart / table / SmartArt placeholders with the right names and counters; positions and dimensions all correct in inches.
