i have 3 inputs to upload 3 diferent images, i want to validate if 2 of the input have uploaded image, then save as pdf, if i have just 1 can save it to pdf. This is my code of JSPdf:

 if(parseInt(img) === 0){
        doc.addImage('JPEG', 16,110,85,85);
        } else {
            doc.addImage(img2, 'JPEG', 110,110,85,85);
            doc.addImage(img3, 'JPEG', 16,200,85,85);
        } 

        if(parseInt(img2) === 0){
            doc.addImage('JPEG', 110,110,85,85);
        } else {
            doc.addImage(img, 'JPEG', 16,110,85,85);
            doc.addImage(img3, 'JPEG', 16,200,85,85);
        } 
        
        if(parseInt(img3) === 0){
            doc.addImage('JPEG', 16,200,85,85);
        } else {
            doc.addImage(img, 'JPEG', 16,110,85,85);
            doc.addImage(img2, 'JPEG', 110,110,85,85);
        } 

doc.save('mypdf.pdf');

img, img1 and img2 works if i upload the 3 images at same time but if i upload just 1 or 2 it doesn't work.

When i use this code:

      doc.addImage(imagen, 'JPEG', 16,110,85,85);
      doc.addImage(imagen2, 'JPEG', 110,110,85,85);
      doc.addImage(imagen3, 'JPEG', 16,200,85,85);

Works great but only if ai upload the 3 img at same time, if i try to upload just one or two not working.
