How to insert a link? And is it possible?

Question

PDF

Such a problem is a pdf file, how to insert a link to a jpg image that is in the same folder? The main thing is that the link does not break when moving a pdf-ki (with a picture) to another folder. Putting a picture in pdf is not an option, since there is a graph and its size will change from 50x100 to 2000x100 pixels, and in pdf it should always be in a certain place.
(Maybe you can shove this chart into a pdf, and in the pdf, at the place where the chart is, there will be just a link, when you click on which the chart opens, it will be stored in a pdf file. This is generally a stoned option, but if so, tell me how to do it)
Before that with pdf did not work and did not come across. Maybe there are alternatives.
Or maybe there are alternative ways to solve this problem of memory :)
