Hello, good work! Can you select which sheet the image will be inserted on?

@NitemareReal Hi thanks!
I think no, when I had done this I only had need one single sheet, I didn't test to build more sheets, but I think every image you add will repeat on every single sheet in same col/row position.
i'm sorry 😔

I have just tested it and image is just shown in first sheet...

I finally fond out why image is just shown in first sheet while there are "drawingX.xml" and "_rels/drawingX.xml.rels" for every sheet... the problem is when you call "finalizeSheet". Second argument ($i) is incremental, for every sheet, but that's a mistake. This value is used in "finalizeSheet" to write the "drawing" tag, but its r:id should match the id created by "buildSheetRelationshipXML" (which starts from 1 for every sheet). And I think (not verified yet) that "buildSheetRelationshipXML" shouldn't create a "Relationship Id" for every image, it should create only one, and "buildDrawingRelationshipXML" should create all "Relations" to every image in one sheet (pointing to media folder). Fixed that, should be very easy modifing all methods, starting with "addImage", allowing to specify which "sheet" you want to add image to, as original XLSXWriter methods do. Maybe tomorrow i'll try to implement these changes...

It make sense, if you want to fork this I appreciate it or maybe directly on the original repo, but I think it is now archived or in any case no longer followed

Done! I forked from your fork. Now you can add multiple images to a sheet and specify which sheet will image(s) insert on!
I have tested it and it works!

New changes to show the picture with its original size if no end coordinates given
