Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I'm not Dave, and since he seems to have not picked up on this case very promptly, I feel I should offer what help I can.
The general difficulty you are running into is like this:
1. any photo file on your computer, e.g. a JPEG or JPG type file, has a width (in pixels) and a height (in pixels.)
"Pixels" might be seen, simply, as 'dots'. Dots of color.
2. as displayed on a website, you can either display them as-they-are (height and width -wise), or more usually, and what seems to be the problem in the context of your question, you can have tags on the website or in the website code, for 'width' (again in pixels) or 'height' (ditto). Those widths and heights, in the website code, can force your picture file to occupy that much space in pixels-high and pixels-wide. So thus, you have distortion of the photo.
A: either you eliminate the tags from the website code, for each image, that specify width and height, and just let the website display the picture as-is with regard to its inherent width and height, or
B: you may redo the picture to that width and height, with photo editing software. For instance, there is the MS Paint (or, Paint) program on all Windows computers. You can load a picture into it, then go to
in the Home tab of the program
which will ask your for a percentage of re-sizing. 100 % means no-change, 50 % means reduce to 1/2 (in height, or width, or usually both, but the height and width percentages can be entered to be different) and 200 % means enlarge by a factor of 2.
Then you can Save As from that program, give the resized pic a new name (in case you need to preserve the original sized version of the photo), save that, ... then post that resized version to your website, so that it is not distorted.
