Buscar vínculos no disponibles en esta carpeta, no funciona bien

Are you trying to replace multiple links by a different image? That cannot be done with that option, it only relinks files that have the same name.

@anamilena I believe you need to select the images in the 'Links' Panel....as you can see, I have an opened a PDF in Illustrator, and I all the files are embedded except for one file which shows a 'chain link' which is linked. I can either select the image and click on the update link or if I have multiple links, I can select all and relink the images to it's folder. As long as the files are named the same, they should update automatically!

Single Linked File - Update

Multiple Files - Relink
