Hi everyone, i think im having a problem with some of my character creator files
The problem is that the images i used for the headshot puglin turned wide/ change resolution after sometime of not opening the file. The example is the following:
1. I made a character to resemble a football player and used the image bellow for the headshot plugin. 

2. I used the image matching tool to improve the result and it came out like the picture above 
3. After afew days i came back to the project an the image used on the headshot plugin had a different resolution, like its stretched out and now its impossible to use the image matching tool. I dindt alter the original picture or create another one with the same name but this already happend in another project of mine that i used a copy pasted image that wasnt even saved in the computer. When i create a new project with the old image it works but i really dont want to start from 0. 
4. My question is, what could have caused this? And is there a way for me to put the image back to its original size so i can go back to using the image matching tool. 
If needed i can show the other example of this happening for a better explantion of the problem.

Thank you guys and i would really aprreciate the help
