Loss of resolution with imread?

I am loading some images to another program using imread, and I have noticed that the resolution for some graphs that are saved as jpeg images is drastically reduced when I load them. Unfortunately it is so reduced that the images are now unsable. Has anyone else run into this problem, and is there any way to remedy it? I have also tried with tif files, but the problem persists.

Switched the image type to pnf and the resolution problem was solved.

IMREAD does not reduce the resolution of the images. The problem must have happened at "save as jpeg". How did you do that?

my image is saved with saveas(gcf, title, 'jpg'), however when I open the jpeg image from its folder the resolution is fine (however, the resolution is definitely better with the pdf version of the file, but I cannot edit this). Opened from the folder the resolution is fine, then displayed once loaded from my program the resolution is drasatically reduced.
